IS31CS8964
DESCRIPTION
IS31CS8964 is a general-purpose microcontroller with extensive peripherals suitable for a wide range of applications. The CPU utilizes an enhanced 1-cycle 8051 core equivalent to ten times the speed of a conventional 12T 8051. The total on-chip memory includes a 2KB SRAM and 64KB embedded flash memory that can be used as program memory which may also serve as the flash memory. The 8051 core has built-in T0/T1/T2/T3/T4/T5 timers and a 30-bit watchdog timer. Embedded in the CPU core are also a full-duplex UART ports, one I2C master/slave and one I2C pure slave controllers, up to 28 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 +/-5%, or a slow power internal 100K Hz oscillator, and an external 4MHz to 24MHz crystal oscillator, or an ultra low power precision real time clock (RTC). Unused clock sources can be disabled or used as GPIO pins for...
