IS31CS8964 Low Standby Power 8051 MCU with 64K/32K/16K Flash and 2K/1K SRAM GENERAL 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.
