PIC16C54A-04/SS

Microcontrollers Overview

The PIC16C54A-04/SS is an 8-bit microcontroller from the PIC16C5X family, featuring a 12-bit wide instruction set and an 8-bit data path. It includes 512 words of EPROM program memory and 25 bytes of RAM. The device operates at a maximum clock frequency of 4 MHz and supports four oscillator configurations: LP, XT, HS, and RC. It provides 12 I/O pins, a Timer0 module with a programmable prescaler, Power-on Reset (POR), Device Reset Timer (DRT), and a Watchdog Timer (WDT). The unit is housed in a 20-pin SSOP package.

Microcontrollers Feature Summary

• High-performance RISC architecture with only 33 single-cycle instructions for efficient code execution.
• Integrated peripheral features including a real-time clock/counter (TMR0) and multiple reset mechanisms to reduce external component requirements.
• Flexible oscillator selection supporting low-cost RC, standard crystal, high-speed crystal, and low-power crystal modes.
• Programmable code protection and power-saving SLEEP mode to enhance system security and energy efficiency.

Microcontrollers Applications

• Automotive and appliance motor control systems
• Low power remote transmitters and receivers
• Telecom processors and pointing devices

Microcontrollers Procurement Notes

Verify the specific suffix 'SS' confirms the SSOP-20 surface mount package type. Confirm the '-04' designation aligns with the required 4 MHz operating speed for your application timing constraints. Check current availability status as older revisions may have limited supply or end-of-life implications. Ensure programming equipment compatibility with EPROM technology if field reprogramming is required.

Microcontrollers Selection Notes

Select this component when a cost-effective, fully static 8-bit solution with EPROM flexibility is needed for development or low-volume production. Consider the 12 I/O pin count against interface requirements. Evaluate the 4 MHz speed limit against processing demands. Compare against OTP versions if permanent programming is sufficient, or ROM versions for high-volume fixed-code applications.

Microcontrollers Part Context

This part belongs to the PIC16C5X series of 8-bit CMOS microcontrollers. It shares architectural similarities with other members like the PIC16C54 and PIC16C56 but differs in memory size and package options. The 'A' revision indicates user-programmable oscillator configuration capabilities within the specified voltage range.

Microcontrollers Replacement Considerations

PIC16CR54A variants offer similar functionality with ROM memory instead of EPROM. Other PIC16C5X family members provide different I/O counts or memory sizes but maintain software compatibility.
