IS32CS8977
DESCRIPTION
CS8977 is a general-purpose MCU with 64KB Code e-Flash memory with ECC and 2KB SRAM with ECC. The embedded flash for code storage has a built-in ECC that corrects one-bit errors and detects two-bit errors. CPU accesses the e-Flash through program address read and through Flash Controller which can perform software read/write operations of e-Flash.
CS8977 has a 1-T 8051 with enhanced multiplication and division accelerator. There are three clock sources for the system. One is a 16MHz/32MHz IOSC (manufacturer calibration+/- 2%), another is XCLK, and the other one is SOSC32KHz (typical 32KHz) which is divided by the slow oscillator. ALL clock sources have a clock programmable divider for scaling down the frequency to save power dissipations. The clock selections are bined with flexible power management schemes, including NORMAL, IDLE, STOP, and SLEEP modes to balance speed and power consumption.
There are T0/T1/T2/T3/T4/T5 timers coupled with CPU and three WDTs where WDT1...
