PIC16C745-I/SO

The PIC16C745/765 devices are low-cost, high-performance, CMOS, fully-static, 8-bit microcontrollers in the PIC16CXX mid-range family. All PICmicro microcontrollers employ an advanced RISC architecture. The PIC16CXX microcontroller family has enhanced core features, eight-level deep stack and multiple internal and external interrupt sources. The separate instruction and data buses of the Harvard architecture allow a 14-bit wide instruction word with the separate 8-bit wide data. The two stage instruction pipeline allows all instructions to execute in a single cycle, except for program branches, which require two cycles. A total of 35 instructions (reduced instruction set) are available. Additionally, a large register set gives some of the architectural innovations used to achieve a very high performance. The PIC16C745 device has 22 I/O pins. The PIC16C765 device has 33 I/O pins. Each device has 256 bytes of RAM. In addition, several peripheral features are available including: three timer/counters, two Capture/Compare/PWM modules and two serial ports. The Universal Serial Bus (USB 1.1) peri
