PIC12LC672-04I/SM

Microcontrollers Overview

The PIC12LC672-04I/SM is an 8-bit microcontroller based on the PIC12C67X family, utilizing One-Time Programmable (OTP) EPROM technology. It features a high-performance RISC CPU with 35 single-cycle instructions and operates at a maximum clock frequency of 4 MHz. The device includes 2048 x 14 words of program memory, 128 bytes of RAM, and five I/O pins. Key peripherals include a four-channel 8-bit Analog-to-Digital Converter (ADC), a Timer0 module with a programmable prescaler, and an internal 4 MHz oscillator with calibration capabilities.

Microcontrollers Feature Summary

• Integrates a four-channel, 8-bit Analog-to-Digital Converter for low-cost analog interface applications.
• Features an internal precision 4 MHz oscillator with programmable calibration to reduce external component requirements.
• Includes special hardware features such as Power-on Reset (POR), Power-up Timer (PWRT), and Oscillator Start-up Timer (OST).
• Supports In-Circuit Serial Programming (ICSP) for flexible code development and production.

Microcontrollers Applications

• Personal care appliances
• Security systems
• Low-power remote transmitters and receivers

Microcontrollers Procurement Notes

Verify the specific ordering suffix against the manufacturer's product identification system to ensure correct voltage range and package type. Confirm that the OTP variant meets production volume needs, as it cannot be reprogrammed after initial programming. Check for any available errata sheets regarding silicon revisions or documentation updates before finalizing procurement specifications.

Microcontrollers Selection Notes

Select this device when a cost-effective solution with integrated ADC and EEPROM-like data retention via software is required. The LC designation indicates operation over a wider voltage range compared to standard C variants. Ensure the application fits within the 2K x 14 word program memory limit and utilizes the available I/O pins effectively. Consider the SOIC-8 package constraints for surface-mount assembly.

Microcontrollers Part Context

This component belongs to the PIC12C67X family of 8-bit CMOS microcontrollers. It shares architectural similarities with other members like the PIC12C671 and PIC12CE673 but differs in memory size and peripheral availability. The family is designed for applications requiring small footprint packages and low power consumption, compatible with the broader PIC16CXXX instruction set architecture.

Microcontrollers Replacement Considerations

Direct substitutes within the same OTP EPROM category include the PIC12C672-10I/SM for higher speed requirements. For devices with EEPROM data memory, consider the PIC12CE672 series if non-volatile data storage is critical. Verify pin compatibility and memory mapping differences when migrating between family members.
