RFPIC12F675F-I/SS

RFPIC12F675F-I/SS Description

The RFPIC12F675F-I/SS from Microchip Technology is an application-specific microcontroller (MCU) integrating RF capabilities with a compact PIC® core architecture. Designed for low-power wireless applications, it combines 1.75KB FLASH program memory and 64 x 8 RAM in a 20-pin SSOP package. Operating within a 2V to 5.5V supply range, it supports FSK/ASK modulation for robust RF communication. As part of the rfPIC™ controller series, it targets embedded wireless systems requiring minimal footprint and energy efficiency. Though marked Obsolete, it remains relevant for legacy designs due to its verified programmability and compliance with ROHS3/REACH standards.

RFPIC12F675F-I/SS Features

• Integrated RF Transceiver: Combines MCU and RF functionality, reducing external components.
• Low-Voltage Operation: 2V–5.5V range enables battery-powered designs.
• Compact Memory: 1.75KB FLASH and 64B RAM for constrained applications.
• 6 I/O Pins: Flexible GPIO for sensor interfacing or control logic.
• Industrial Compliance: EAR99 (export-friendly) and MSL 1 (unlimited shelf life).
• Surface-Mount (SSOP): Ideal for space-constrained PCBs.
• RKE-Optimized: Hardware support for Remote Keyless Entry (RKE) protocols.

RFPIC12F675F-I/SS Applications

1. Remote Keyless Entry (RKE): Low-power RF communication for automotive security.
2. Wireless Security Systems: Door/window sensors, alarm panels with FSK/ASK modulation.
3. IoT Edge Devices: Legacy designs needing MCU+RF integration in a single chip.
4. Consumer Electronics: Low-cost wireless controls (e.g., garage openers).

Conclusion of RFPIC12F675F-I/SS

The RFPIC12F675F-I/SS excels in low-complexity wireless systems by merging a PIC MCU with RF transceiver capabilities. Its obsolete status limits new designs, but it remains a cost-effective solution for RKE and security applications requiring minimal BOM and power consumption. Engineers valuing proven reliability and compliance (ROHS3/REACH) may still leverage this MCU for legacy or niche projects.
