PIC16LC74A-04/L

Microcontrollers Overview

The PIC16LC74A-04/L is an 8-bit CMOS microcontroller from the PIC16C7X family, featuring a low-power EPROM program memory architecture. It provides 4K x 14 words of user-accessible program memory and 192 bytes of data RAM. The device operates with a maximum clock frequency of 4 MHz and supports a wide voltage range of 2.5V to 6.0V. It includes an 8-channel 8-bit analog-to-digital converter, three timer modules, two Capture/Compare/PWM modules, and dual serial communication interfaces (SPI/I²C and USART). The component is housed in a 44-pin PLCC package.

• Includes multiple peripheral modules such as timers, capture/compare/PWM units, and synchronous/asynchronous serial ports.
• Supports In-Circuit Serial Programming for efficient code updates and development.

Microcontrollers Applications

• Appliance control systems requiring low-cost processing
• Security and remote sensor applications
• Automotive electronic modules

Microcontrollers Procurement Notes

Verify that the ordering suffix 'L' corresponds to the specific 44-pin PLCC package configuration required for your PCB layout. Confirm that the '-04' designation aligns with the necessary 4 MHz operating speed limit for your system timing constraints. Ensure compatibility with the 2.5V to 6.0V supply voltage range intended for your application environment.

Microcontrollers Selection Notes

Select this component when a balance of low power consumption and moderate I/O count is required. The 44-pin PLCC package offers a compact footprint suitable for space-constrained designs. Consider the EPROM technology if field reprogrammability or prototype flexibility is needed over the lifetime of the product.

Microcontrollers Part Context

This device belongs to the PIC16C7X family of 8-bit microcontrollers, which are enhanced versions of the earlier PIC16C5X architecture. The family shares common core features such as the eight-level deep hardware stack and interrupt capabilities. The PIC16C74A variant specifically distinguishes itself by offering 33 I/O pins and an integrated Parallel Slave Port compared to smaller variants in the series.
