PIC16F74T-I/PT

Microcontrollers Overview

The PIC16F74T-I/PT is a 40-pin TQFP 8-bit CMOS FLASH microcontroller from the PIC16F7X family. It features a high-performance RISC CPU with up to 20 MHz operating speed and 200 ns instruction cycle time. The device includes 4K x 14 words of FLASH program memory, 192 bytes of data SRAM, and 33 general-purpose I/O pins. Key peripherals include two Capture/Compare/PWM modules, an 8-channel 8-bit Analog-to-Digital converter, SSP (SPI/I2C), USART, and three timers. It operates within a voltage range of 2.0V to 5.5V and supports industrial temperature ranges.

Microcontrollers Feature Summary

• High-performance RISC CPU architecture with single-cycle instruction execution
• In-Circuit Serial Programming (ICSP) capability via two pins
• Integrated Brown-out Reset (BOR) and programmable code protection
• Parallel Slave Port (PSP) for direct microprocessor bus interfacing

Microcontrollers Applications

• Industrial control systems requiring robust reset features
• Embedded applications utilizing parallel slave port communication
• Motor control designs using CCP modules for PWM generation
• Data acquisition systems leveraging the 8-channel A/D converter

Microcontrollers Procurement Notes

Verify that the ordering suffix 'T' corresponds to tape-and-reel packaging and '/PT' indicates the 44-pin TQFP package variant. Confirm the '-I' suffix denotes the industrial temperature range specification. Ensure compatibility with existing PCB footprints for the specified package dimensions before finalizing procurement orders.

Microcontrollers Selection Notes

Select this component when 4K program memory and 192 bytes RAM are sufficient for the application logic. Choose this part over the PIC16F73 or PIC16F76 if additional I/O lines and analog channels are required. Consider the PIC16F77 only if 8K program memory is necessary, as the functional core remains identical across the family.

Microcontrollers Part Context

This device belongs to the PIC16F7X series, which shares a common mid-range architecture. It is pin-compatible with the older PIC16C74B and PIC16F874 devices, facilitating migration from legacy designs. The family distinguishes itself through integrated FLASH technology and comprehensive peripheral sets suitable for complex embedded tasks.

Microcontrollers Replacement Considerations

Direct pin-compatible replacements include the PIC16F74 in DIP or PLCC packages. For legacy upgrades, the PIC16C74B and PIC16F874 offer compatible pinouts but may differ in electrical characteristics or memory endurance specifications.
