LC823430TA
CMOS LSI
Audio Processing System LSI
for MP3 Record and Playback Devices
http://onsemi.com
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)

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.
* I2C Bus is a trademark of Philips Corporation.
