LC823433TA

Overview

LC823433TA 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)

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)

- 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).
