P89C660; P89C662; P89C664; P89C668 80C51 8-bit Flash Microcontroller Family 16KB/32KB/64KB ISP/IAP FLASH With 512B/1KB/2KB/8KB RAM

The P89C660 P89C662; P89C664; P89C668 device contains a non-volatile 16KB/32KB/64KB Flash program memory that is both parallel programmable and serial In-System and In-Application Programmable. In-System Programming (ISP) allows the user to download new code while the Microcontroller sits in the application. In-Application Programming (IAP) means that the Microcontroller fetches new program code and reprograms itself while in the system. This allows for remote programming over a modem link. A default serial loader (boot loader) program in ROM allows serial In-System Programming of the Flash memory via the UART without the need for a loader in the Flash code. For In-Application Programming, the user program erases and reprograms the Flash memory by use of standard routines contained in ROM. This device executes one instruction in 6 Clock cycles, hence providing twice the speed of a conventional 80C51. An OTP configuration bit gives the user the option to select conventional 12-clock Timing This device is a Single-Chip 8-Bit Microcontroller manufactured in advanced CMOS process and is a derivative of the 80C51 Microcontroller family. The instruction set is 100 pct executing and Timing compatible with the 80C51 instruction set. The device also has four 8-bit I/O ports, three 16-bit Timer event Counters a multi-source, four-priority-level, nested interrupt structure, an enhanced UART and on-chip Oscillator and Timing circuits. The added features of the P89C660 P89C662; P89C664; P89C668 makes it a powerful Microcontroller for applications that require pulse width modulation, high-speed I/O and up/down counting capabilities such as Motor Control
