IS31CS5523
DESCRIPTION
IS31CS5523 is a general-purpose microcontroller with 64K embedded flash memory and 2K SRAM. Extensive peripherals are included targeted for embedded system with LCD/LED displays. The CPU is based on 1-T 8051 with T0/T1/T2 and additional 16-bit T3/T4, 24-bit T5 and a 30-bit WDT. Embedded in the CPU core are also a full-duplex UART port, an enhanced EUART port with LIN capability, one I2C master/slave and two I2C pure slave controllers, one SPI mater/slave controller, up to 55 GPIO pins with each GPIO pin configurable as external interrupt and wake up.
The flexibility in clock setting includes an on-chip precision oscillator with the accuracy deviation of +/-2%, or a low power internal 32KHz oscillator, or an ultra low power precision real time clock (RTC) and a programmable PLL up to 10MHz. The clock selections are bined with flexible power management schemes, including NORMAL, PMM, IDLE, and STOP, and SLEEP modes to balance CPU speed and power consumption.
