描述 Description

IS31CS8968A is a general-purpose microcontroller with extensive peripherals suitable for a wide range of applications. The CPU is based on an enhanced 1-cycle 8051 core equivalent to ten times the speed of a conventional 12-T 8051. The total on-chip memory include 6KB SRAM and a total of 128KB embedded flash memory that can be used as program memory and portion of this can be used as data flash. The 8051 core has built-in T0/T1/T2 timers, 24-bit T3 timer, 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 42 GPIO pins.
