LOW POWER 3-CHANNEL SOUND CONTROLLER
1. GENERAL DESCRIPTION
3. FEATURES
GPC3LXXXX is embedded with an 8-bit processor, 288K~512K
bytes ROM and 256-byte working SRAM, three 12-bit
timer/counters, 20 general I/Os, a 3-channel mixer, a pair of 12-bit
PWM outputs and a Real Time Clock(RTC). GPC3LXXXX is
designed for wide input voltage (1.0V~1.8V; 1.3V~3.6V), and the
circuit works at a programmable pumped voltage (2.7V~4.5V). In
audio processing, both melody and speech is capable of being
mixed together into one output. Furthermore, it contains a Low
Voltage Reset to assure system operating appropriately under low
voltage condition and a sleep mode to save power while system is
standing by. With a high cost/performance ratio characteristic,
GPC3LXXXX is one of the most suitable engines in the industry
for vocal applications.

7. FUNCTIONAL DESCRIPTIONS
7.1. CPU
7.5. I/O Port
The microprocessor inside the GPC3LXXXX is an 8-bit high
performance processor equipped with Accumulator, Program
Counter, X and Y Register, Stack pointer and Processor Status
Register (the same as CPU6502 instruction structure). The
maximum CPU speed of 8.0MHz is capable of generating clearer
speech, pleasant music as well as achieving the best
performance.
There are 20 IOs (IOA[7:0], IOB[7:0] and
GPC3LXXXX, which are bit-control IOs.
IOC[3:0] in
They can be
programmed as input (pure input or pull-low) or output buffer. As
pull-low input, they keep a less impedance to get better noise
immunity. While pressing the key (IOs to VDD), a less or large
impedance can be selected at different conditions. IOA7 can be
programmed as an IR transmitter. IOA[4:3] can be programmed as
Detect IO. IOA[2:1] can also be programmed as feedback
function with IOA2 connecting to the input of inverter and IOA1
connecting to the output of inverter. With feedback function, RC
or XTAL oscillation can be implemented. For more flexible
application, IO wakeup and ECK as TMA clock source are also
7.2. RAM Area
The RAM size in GPC3LXXXX is 256-byte (including Stack), in
which address starts from $0080 through $017F ($0100 - $017F
mapping to $0180 - $01FF).
available when feedback function enable.
Please refer to
programming guide for more detailed information about feedback
function. IOA1 can be programmed as an external clock source.
IOA0 is programmable as an external interrupt source. IOB5 and
IOB4 can be programmed as a 32KHz crystal clock generator by
7.3. ROM Area
GPC3LXXXX builds a 288K~512K bytes of ROM, which can be
defined as the program area, audio data area, or both. To access
ROM, users shall program the BANK SELECT register, choose
bank, and access address to fetch data.

those applications requiring low standby current.
To enter
standby mode, the Wake-up Register must be enabled and then
stop the CPU clock by writing the STOP CLOCK Register to enter
standby mode. In such mode, RAM and I/Os will remain in their
prior states until being awakened. All 20 IOs, RTC (8Hz/2Hz),
and external interrupt (IOA0) are wake-up sources in
GPC3LXXXX. After GPC3LXXXX wakes up, the internal CPU
will proceed to execute the program.

7.8. RTC (Real Time Clock)
7.12. Timer/Counter
GPC3LXXXX provides two RTC (real time clock) sources: 2Hz,
8Hz. The RTC sources can be used for time counting or system
awaking function. Each RTC occurs, system wakes up and users
can use this signal for time counting. In addition, GPC3LXXXX
supports 32768Hz OSC in auto mode; the first one second, it runs
at strong mode (consumes the highest power) and then switches
to weak mode automatically to save power.
GPC3LXXXX has three 12-bit timer/counters: TMA, TMB, and
TMC respectively. In timer mode, TMA, TMB, and TMC are
re-loadable up-counters. When timer overflows from $0FFF to
$0000, the carry (overflow) signal will make the user’s pre-set
value to be loaded into timer automatically and count up again.
At the same time, the carry signal will generate an INT signal if the
corresponding bit in the INT ENABLE Register is enabled.
Suppose TMB is specified as a counter, users can reset it by
loading #0 into the counter. After the counter is activated, the
counter value can also be read at the same time. The read
instruction will not affect the counter value nor reset it.
7.9. Watchdog
The purpose of watchdog is to monitor whether the system
operates normally. Within a certain period, watchdog must be
cleared. It prevents system from incorrect code execution by
generating a system reset when software fails to clear watchdog
flag within 1 second. Watchdog function can be removed by
option in GPC3LXXXX series.
7.13. Speech and Melody
In speech synthesis, the GPC3LXXXX can use NMI for accurate
sampling frequency. User can store the speech data in ROM and
play it back with realistic sound quality. Several algorithms are
recommended for high fidelity and compression of sound: PCM,
ADPCM, SACMA3400 and A3400Pro.
7.10. Low Voltage Reset
GPC3LXXXX has a Low Voltage Reset (LVR) function. In
general, CPU becomes unstable and abnormal under low voltage
condition. With the unique design of Low Voltage Reset in
GPC3LXXXX, it is able to reset all functions to the initial
operational (stable) state if the power voltage drops below certain
operation voltage.
7.14. Battery voltage detect function
GPC3LXXXX has Battery Voltage Detection (BVD) function.
There are four detecting levels can be chosen for 1-battery and
2-battery application respectively. Please refer to programming
guide for more detailed information about BVD function.
7.11. Interrupt
GPC3LXXXX has two interrupt (INT) modes: IRQ (interrupt
Request) and NMI (Non-Mask Interrupt Request). The interrupt
controller provides 9 IRQs and 1 NMI. A NMI cannot be
interrupted by any other IRQs.

PCB Layout Guidelines :
1. R1 (used for ROSC) should be as close as possible to IOC0 pin.
2. C3 should be as close as possible to PVDD/PVSS, and C3 can be removed if there is good power line layout on PCB that
no harm to sound quality.
3. The value of C2 depends on the loading. 10uF~47uF is the suggested value range. One end of C2 should be placed between
VSS1, VSS2, VSS3 and VSS15. The other end of C2 should be placed between VDDO, VDDIO and VDD. C2 should be as
close as possible to VDDO/VDDIO/VDD
4. Net between LX1 and LX2 should be as short as possible.
5. L should be as close as possible to VDD15/LX1/LX2. Please use inductance with lower resistance to gain higher
efficiency, 22uH/0.5W@IDC(max)>250mA, DCR<1 ohm is the suggested inductance spec.
6. R2 and C1 could be removed if do not care BVD flag vibration due to VDD15 bouncing.
7. These capacitor values are for design guidance only. The recommended 32K XTAL features are ESR=11.2~60K and
CL1=CL2 =26~36pF (including PCB parasitic loading, for example, user should apply additional 20~30pF on X32I and X32O
if PCB parasitic loading is 6pF).
8. Please use capacitor (C2) with lower resistance to reduce noise, ESR<2 ohm in 0~70C is suggested.

PCB Layout Guidelines :
1. R1 (used for ROSC) should be as close as possible to IOC0 pin.
2. C3 should be as close as possible to PVDD/PVSS, and C3 can be removed if there is good power line layout on PCB that
no harm to sound quality.
3. C5 should be as close as possible to VDDIO/VSS1, and C5 can be removed if there is good power line layout on PCB
that the power stable enough.
4. The value of C6 depends on the loading. 4.7uF~100uF is the suggested value range. C6 should be as close as possible to
VDD/VSS2, and C6 can be smaller if there is good power line layout on PCB that the power stable enough.
5. Net between LX1 and LX2 should be as short as possible.
6. L should be as close as possible to VDD15/LX1/LX2. Please use inductance with lower resistance to gain higher
efficiency, 22uH/0.5W@IDC(max)>250mA ,DCR<1 ohm is the suggested inductance spec.
7. R2 and C1 could be removed if do not care BVD flag vibration due to VDD15 bouncing.
8. R3 with 0 Ohm is suggested for 2 batteries or C6 > 10uF and with 1 Ohm is suggested for 1 battery and C6 < 10uF.
9. These capacitor values are for design guidance only. The recommended 32K XTAL features are ESR=11.2~60K and
CL1=CL2 =26~36pF (including PCB parasitic loading, for example, user should apply additional 20~30pF on X32I and X32O
