PIC16C65B-04/PQ IC MCU 8BIT 7KB OTP 44MQFP

Description

The PIC16C63A/65B/73B/74B 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 PIC16C63A/73B devices have 22 I/O pins. The PIC16C65B/74B devices have 33 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 Universal Synchronous Asynchronous Receiver Transmitter (USART) is also known as the Serial Communications Interface or SCI. Also, a 5- channel high speed 8-bit A/D is provided on the PIC16C73B, while the PIC16C74B offers 8 channels. The 8-bit resolution is ideally suited for applications requiring low cost analog interface, e.g., thermostat control, pressure sensing, etc.
