CS8953

CS8953 Preliminary 8051 Embedded Micro-Controller with 32KB Flash ROM GENERAL DESCRIPTION CS8953 is a general purpose microcontroller with extensive peripherals that are suitable for wide range of application. The CPU is based on an enhanced 1Cycle 8051 core that is equivalent to 10 times faster than a conventional 12-Cycle 8051. Total on-chip SRAM is 1KB for data storage. There is total 32KB of 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 and a 16-bit watchdog timer. Embedded in the CPU core are also two full-duplex UART ports, one I2C master controller, and up to 28 GPIO, and up to 8 external interrupts. Flexibility in clock includes an on-chip precision oscillator that have +/-2% accuracy or ultra low power real time clock, and regular crystal oscillator. Unused clock sources can be disabled or used as GPIO pins for best system optimization. The clock selections are also combined w...
