PIC12F609-I/P

Microcontrollers Overview

The PIC12F609-I/P is an 8-bit Flash-based microcontroller in the PIC12 family, housed in an 8-pin PDIP package. It features a high-performance RISC CPU with 35 instructions and operates at speeds up to 20 MHz. The device includes 1K x 14 words of Flash program memory and 64 bytes of SRAM data memory. Key peripherals include a precision internal oscillator (factory calibrated to ±1%), an analog comparator, Timer0, and Timer1. It supports industrial temperature ranges and offers low-power Sleep mode operation.

Microcontrollers Feature Summary

• Precision Internal Oscillator: Factory calibrated to ±1% typical accuracy with software-selectable frequencies of 4 MHz or 8 MHz.
• High-Performance RISC CPU: Features only 35 single-cycle instructions except branches, an 8-level deep hardware stack, and interrupt capability.
• Robust Memory Endurance: Provides 100,000 write endurance for Flash program memory with retention exceeding 40 years.
• Low-Power Operation: Includes Power-Saving Sleep mode with standby current as low as 50 nA at 2.0V.

Microcontrollers Applications

• Clock and timing circuits
• Embedded design and development
• Industrial control systems
• Portable battery-operated equipment

Microcontrollers Procurement Notes

Verify the ordering suffix 'I' corresponds to the Industrial temperature range (-40°C to +85°C) and 'P' indicates the 8-pin PDIP package. Confirm that the specific revision matches the DS41302D datasheet. Ensure compatibility with In-Circuit Serial Programming (ICSP) requirements for your development environment.

Microcontrollers Selection Notes

Select this component when a compact 8-pin solution is required for basic logic control without analog-to-digital conversion needs. It is suitable for applications prioritizing code protection and low standby power over high-speed processing. Compare against PIC12F615 if ADC or ECCP modules are necessary for the application.

Microcontrollers Part Context

This part belongs to the PIC12F609/615/617 series, which are protected by Microchip’s Low Pin Count patent. These devices share a common architecture but differ in peripheral sets; the PIC12F609 specifically lacks the A/D converter found in the PIC12F615/617 variants.

Microcontrollers Replacement Considerations

Direct pin-compatible replacements within the same package include other PIC12F609 variants with different temperature grades (e.g., E for Extended). For functional upgrades requiring ADC, consider the PIC12F615, though peripheral differences must be accounted for in firmware.

Microcontrollers FAQ

Does the PIC12F609 include an Analog-to-Digital Converter?

No, the PIC12F609 does not have an A/D module. This feature is available in the PIC12F615 and PIC12F617 variants of the same family.

What is the maximum operating speed of the internal oscillator?

The precision internal oscillator can be software-selected to operate at either 4 MHz or 8 MHz.
