PIC16F818 Microcontroller

The PIC16C63A devices are low cost, high performance, CMOS, fully-static, 8-bit microcontrollers in the PIC16CXX mid-range family. All PIC? 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 PIC16C63 devices have 22 I/O pins. Each device has 192 bytes of RAM. In addition, several peripheral features are available, including: three timer/ counters, two Capture/Compare/PWM modules, and two serial ports. The Synchronous Serial Port (SSP) can be configured as either a 3-wire Serial Peripheral Interface (SPI) or the two-wire Inter-Integrated Circuit (I2C) bus.

The PIC16C83A is 8-Bit CMOS EEPROM Microcontrollers?Transceiver. PIC16C83A microcontrollers typically achieve a 2:1 code compression and up to a 2:1 speed improvement (at 10 MHz) over other 8-bit microcontrollers in their class. The PIC16C83A has up to 68 bytes of RAM, 64 bytes of Data EEPROM memory, and 13 I/O pins. A timer/counter is also available.
