RFPIC12F675F-I/SS

Overview

The rfPIC12F675F-I/SS is a 20-pin SSOP flash-based microcontroller integrating an ASK/FSK UHF transmitter. It features a high-performance RISC CPU with 35 instructions, operating at DC to 20 MHz. Memory includes 1024 x 14 words of FLASH program memory, 128 bytes of EEPROM, and 64 bytes of SRAM. The device supports a wide voltage range of 2.0 V to 5.5 V. Peripherals include four 10-bit ADC channels, two timers, an analog comparator, and six I/O pins. The integrated transmitter operates in the 380-450 MHz band with output power adjustable from +10 dBm to -12 dBm.

Procurement Notes

Verify the specific 'F' suffix indicates the 380-450 MHz frequency variant. Confirm the '-I' designation corresponds to the industrial temperature range (-40°C to +85°C). Ensure the '/SS' package matches the required 20-pin SSOP form factor for the design.

Selection Notes

Select this component for designs requiring an integrated MCU and RF transmitter in a compact package. The 380-450 MHz frequency band suits regional ISM regulations. Consider the 64-byte RAM limit for complex firmware. Verify antenna matching requirements for the integrated RF power amplifier.

Part Context

This part belongs to the rfPIC12F675 family, which includes variants for different frequency bands: K (290-350 MHz), F (380-450 MHz), and H (850-930 MHz). All variants share the same core architecture and peripheral set but differ in their RF oscillator configurations.
