Description

Description
The AT28C010 is a high‑performance Electrically Erasable and Programmable Read‑Only Memory (EEPROM).
Its 1‑Mb memory is organized as 131,072 words by 8 bits. Manufactured with Microchip’s advanced nonvolatile
CMOS technology, the device offers access times to 120 ns with power dissipation of just 440 mW. When the device
is deselected, the CMOS standby current is less than 300 µA.
The AT28C010 is accessed like a Static RAM for the read or write cycle without the need for external components.
The device contains a 128‑byte page register to allow writing of up to 128 bytes simultaneously. During a write cycle,
the address and 1 to 128 bytes of data are internally latched, freeing the address and data bus for other operations.
Following the initiation of a write cycle, the device will automatically write the latched data using an internal control
timer. The end of a write cycle can be detected by DATA Polling of I/O7. Once the end of a write cycle has been
detected, a new access for a read or write can begin.
The AT28C010 has additional features to ensure high quality and manufacturability. The device utilizes internal error
correction for extended endurance and improved data retention characteristics. An optional software data protection
mechanism is available to guard against inadvertent writes. The device also includes an extra 128 bytes of EEPROM
for device identification or tracking.

Device Operation
5.
Device Operation
READ: The AT28C010 is accessed like a Static RAM. When CE and OE are low and WE is high, the data stored at
the memory location determined by the address pins is asserted on the outputs. The outputs are put in the high-
impedance state when either CE or OE is high. This dual-line control gives designers flexibility in preventing bus
contention in their system.
BYTE WRITE: A low pulse on the WE or CE input with CE or WE low (respectively) and OE high initiates a write
cycle. The address is latched on the falling edge of CE or WE, whichever occurs last. The data is latched by the first
rising edge of CE or WE. Once a byte write is started, it will automatically time itself to completion. Once a
programming operation is initiated and for the duration of tWC, a read operation will effectively be a polling operation.
PAGE WRITE: The page write operation of the AT28C010 allows 1 to 128 bytes of data to be written into the device
during a single internal programming period. A page write operation is initiated in the same manner as a byte write;
the first byte written can then be followed by 1 to 127 additional bytes. Each successive byte must be written within
150 µs (tBLC) of the previous byte. If the tBLC limit is exceeded, the AT28C010 will cease accepting data and
commence the internal programming operation. All bytes during a page write operation must reside on the same
page as defined by the state of the A7‑A16 inputs. For each WE high‑to‑low transition during the page write
operation, A7‑A16 must be the same. The A0 to A6 inputs are used to specify which bytes within the page are to be
written. The bytes may be loaded in any order and may be altered within the same load period. Only bytes which are
specified for writing will be written; unnecessary cycling of other bytes within the page does not occur.
DATA POLLING: The AT28C010 features DATA Polling to indicate the end of a write cycle. During a byte or page
write cycle, an attempted read of the last byte written will result in the complement of the written data to be presented
on I/O7. Once the write cycle has been completed, true data is valid on all outputs, and the next write cycle may
begin. DATA Polling may begin at anytime during the write cycle.
TOGGLE BIT: In addition to DATA Polling, the AT28C010 provides another method for determining the end of a write
cycle. During the write operation, successive attempts to read data from the device will result in I/O6 toggling
between one and zero. Once the write has completed, I/O6 will stop toggling and valid data will be read. Reading the
toggle bit may begin at any time during the write cycle.
DATA PROTECTION: If precautions are not taken, inadvertent writes may occur during transitions of the host system
power supply. Microchip incorporated both hardware and software features that will protect the memory against
inadvertent writes.
HARDWARE PROTECTION: Hardware features protect against inadvertent writes to the AT28C010 in the following
ways:
•
•
VCC sense – if VCC is below 3.8V (typical), the write function is inhibited
VCC power‑on delay – once VCC has reached 3.8V, the device will automatically time out 5 ms (typical) before
allowing a write
•
•
write inhibit – holding any one of OE low, CE high or WE high inhibits write cycles
noise filter – pulses of less than 15 ns (typical) on the WE or CE inputs will not initiate a write cycle
SOFTWARE DATA PROTECTION: A software-controlled data protection feature has been implemented on the
AT28C010. When enabled, the software data protection (SDP) will prevent inadvertent writes. The SDP feature may
be enabled or disabled by the user; the AT28C010 is shipped with SDP disabled.
SDP is enabled by the host system issuing a series of three write commands; three specific bytes of data are written
to three specific addresses (refer to Software Data Protection Algorithm). After writing the 3‑byte command sequence
and after tWC, the entire AT28C010 will be protected against inadvertent write operations. It should be noted that,
once protected, the host may still perform a byte or page write to the AT28C010. This is done by preceding the data
to be written by the same 3‑byte command sequence used to enable SDP.
Once set, SDP will remain active unless the disable command sequence is issued. Power transitions do not disable
SDP and SDP will protect the AT28C010 during power‑up and power‑down conditions. All command sequences must
conform to the page write timing specifications. The data in the enable and disable command sequences is not
written to the device and the memory addresses used in the sequence may be written with data in either a byte or
page write operation.

AT28C010
Device Operation
After setting SDP, any attempt to write to the device without the 3‑byte command sequence will start the internal write
timers. No data will be written to the device; however, for the duration of tWC, read operations will effectively be polling
operations.
DEVICE IDENTIFICATION: An extra 128 bytes of EEPROM memory are available to the user for device
identification. By raising A9 to 12V ± 0.5V and using address locations 1FF80H to 1FFFFH, the bytes may be written
to or read from in the same manner as the regular memory array.
OPTIONAL CHIP ERASE MODE: The entire device can be erased using a 6‑byte software code. See Software Chip
Erase application note for details.

3. tDF is specified from OE or CE, whichever occurs first (CL = 5 pF).
4. This parameter is characterized and is not 100% tested.

Microchip Devices Code Protection Feature
Note the following details of the code protection feature on Microchip devices:
•
•
Microchip products meet the specification contained in their particular Microchip Data Sheet.
Microchip believes that its family of products is one of the most secure families of its kind on the market today,
when used in the intended manner and under normal conditions.
•
There are dishonest and possibly illegal methods used to breach the code protection feature. All of these
methods, to our knowledge, require using the Microchip products in a manner outside the operating
specifications contained in Microchip’s Data Sheets. Most likely, the person doing so is engaged in theft of
intellectual property.
•
•
Microchip is willing to work with the customer who is concerned about the integrity of their code.
Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code
protection does not mean that we are guaranteeing the product as “unbreakable.”
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection
features of our products. Attempts to break Microchip’s code protection feature may be a violation of the Digital
Millennium Copyright Act. If such acts allow unauthorized access to your software or other copyrighted work, you
may have a right to sue for relief under that Act.
