Overview
LC823430TA is an audio processing system for MP3 record and playback devices.
It integrates DSP for digital signal processing and analog blocks such as audio ADC, audio DAC, and speaker and
headphone amplifier in addition to LCD segment driver.
Features
 32bit LPDSP32
- SRAM (246KB)
 PM 75KB (40KB + 35KB : ISOLATED)
 DMA 170KB (16KB + 154KB : ISOLATED)
 DMB 1KB (ISOLATED)
ISOLATED area : Power ON/OFF control is available by register.
- ROM (264.5KB)
 PM 227.5KB (ISOLATED)
 DMA 34KB (ISOLATED)
 DMB 3KB (ISOLATED)
TQFP128L(14X14)
ISOLATED area : Power ON/OFF control is available by the register.
- SIO (Clock Serial IO 2ch)
 SIO0 : Ch0 eSIO (Clock speed = Sysclk/1 (max))
program load and execute is possible using Serial Flash (after internal ROM Boot)
 SIO1 : Ch1 SIO (Clock speed = Sysclk/8 (max))
- UART (1ch)
- I²C (1ch Single Master, Full/Standard)
- Plain Timer (2ch)
 Timer0 : w/ Watch Dog Timer
 Timer1 : w/o Watch Dog Timer and XT1 operation
- Multiple Timer (2ch)
PWM output (1ch)
- RTC (Real Time Clock)
Operating voltage is independent of internal core operating voltage.
Only RTC power supply can be active during all others inactive (ISOLATED).
- SD card IF (2ch) (w/o CPRM)
eSD/eMMC can be connected.
 SD ch0 : program load and execute using eSD/eMMC (after internal ROM Boot) is possible.
 SD ch1 : SD card
- USB2.0 (480Mbps/12Mbps) Device IF. built-in PHY
- 10bit A/D converter (3ch)
- GPIO (31ch)
(GPIOs share the terminals with other functions. Refer to the terminal list in detail).
 LCD controller, LCD Driver. 18SEG * 8COM, 1/8Duty, 1/4Bias
- Internal ROM Boot is possible.
