RFPIC12F675H-I/SS

Overview

The rfPIC12F675H-I/SS is a high-performance 8-bit microcontroller with an integrated UHF ASK/FSK transmitter, housed in a 20-pin SSOP package. It features a RISC CPU operating at up to 20 MHz, supported by 1 KB of Flash program memory, 128 bytes of EEPROM, and 64 bytes of SRAM. The device includes four 10-bit ADC channels, two timers, and an analog comparator. The RF section operates in the 850-930 MHz band, offering output power from +10 dBm to -12 dBm. It supports industrial temperature ranges (-40°C to +85°C) and functions within a 2.0V to 5.5V supply voltage.

Procurement Notes

Verify component authenticity through authorized Microchip distributors or direct manufacturer channels. Confirm the specific 'H' suffix indicates the 850-930 MHz frequency range variant. Check for RoHS compliance documentation and ensure storage conditions meet humidity sensitivity requirements prior to assembly.

Selection Notes

Select this model specifically for applications requiring operation in the 850-930 MHz ISM band. Ensure the design accommodates the 20-pin SSOP footprint. Verify that the required RF output power levels between +10 dBm and -12 dBm align with system range needs. Consider the 2.0V to 5.5V operating voltage range for power supply design.

Part Context

This component belongs to the rfPIC12F675 family, which differentiates models by operating frequency: K (290-350 MHz), F (380-450 MHz), and H (850-930 MHz). The '-I' designation indicates the Industrial temperature range (-40°C to +85°C), while '/SS' specifies the 20-pin Shrink Small Outline Package.

Replacement Considerations

For frequency-specific replacement, use rfPIC12F675K-I/SS for 290-350 MHz or rfPIC12F675F-I/SS for 380-450 MHz. Non-RF equivalents like the PIC12F675 lack the integrated transmitter and are not functionally compatible for wireless applications.
