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) - 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. Continued on next page.
