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
TQFP128 14x14 / TQFP128L
- 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)
- 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).
