RFPIC12F675FT-I/SS027

Overview

The rfPIC12F675FT-I/SS is an RF microcontroller from Microchip Technology, designed for short-range wireless applications. It integrates a UHF ASK/FSK transmitter with an 8-bit PIC core. The device features 1.75 kB of Flash program memory and 64 bytes of RAM. It operates within a voltage range of 2 V to 5.5 V and supports clock frequencies up to 20 MHz. The component is housed in a 20-lead SSOP package and is rated for industrial temperature ranges.

Feature Summary

• Integrated UHF ASK/FSK short-range radio transmitter
• High-performance 8-bit RISC CPU with 35 instructions
• Factory calibrated internal 4 MHz oscillator (±1% accuracy)
• 100,000 write endurance for Flash and 1,000,000 for EEPROM

Applications

• Short-range low power wireless embedded systems
• Data transmission between embedded devices
• Radio controlled robots
• General purpose remote control interfaces

Procurement Notes

Verify the specific suffix '027' against official Microchip documentation, as standard listings typically use 'I/SS'. Confirm current availability status, as some variants may be discontinued or have restricted supply. Ensure the SSOP-20 package matches the design footprint requirements.

Selection Notes

Select this component for applications requiring integrated RF transmission without external transceivers. Compare with the standard PIC12F675 if RF functionality is not needed. Verify that the 20 MHz maximum clock speed and 6 I/O pins meet the system interface requirements.

Part Context

This part belongs to the rfPIC12F series, which combines standard PIC microcontroller capabilities with embedded RF transmission. It is distinct from the base PIC12F675 by its integrated transmitter, targeting wireless sensor networks and simple telemetry links.

Replacement Considerations

Direct pin-to-pin replacements are limited due to the integrated RF transmitter. Standard PIC12F675 variants lack RF capability. External RF modules paired with standard MCUs may serve as functional alternatives for non-integrated designs.
