PIC16F88T-I/SO

Microcontrollers Overview

The PIC16F88T-I/SO is an 18-pin, 8-bit Flash-based microcontroller from the Mid-Range family. It features 4K x 14 bytes of program memory, 368 bytes of RAM, and 256 bytes of Data EEPROM. The device supports a maximum clock frequency of 20 MHz and operates within a voltage range of 2.0V to 5.5V. Key peripherals include a 10-bit, 7-channel ADC, two analog comparators, one CCP module, an AUSART, and an SSP module with SPI/I²C capabilities.

Microcontrollers Feature Summary

• Integrated low-power management modes including RC_RUN, SEC_RUN, and Sleep for optimized energy consumption.
• Built-in internal oscillator block providing eight selectable frequencies ranging from 31 kHz to 8 MHz.
• Supports In-Circuit Serial Programming (ICSP) and In-Circuit Debugging via dedicated pins.
• Includes fail-safe clock monitor to maintain operation if the primary clock source fails.

Microcontrollers Applications

• Real-time clock applications utilizing the low-power Timer1 oscillator.
• RS-232 communication systems using the internal oscillator without external crystals.
• Motor control and PWM generation via the Capture/Compare/PWM module.
• Sensor interface designs requiring analog-to-digital conversion and comparator functions.

Microcontrollers Procurement Notes

Verify that the 'T' suffix indicates tape and reel packaging suitable for automated surface-mount assembly. Confirm the 'I' designation corresponds to the industrial temperature range of -40°C to +85°C. Ensure the SO package matches the required 18-pin footprint on the target PCB layout.

Microcontrollers Selection Notes

Select this component when a balance of moderate program memory and rich peripheral sets is required. It is suitable for designs needing multiple serial interfaces and analog inputs. Consider the enhanced flash endurance and data retention specifications for long-life embedded applications.

Microcontrollers Part Context

This part belongs to the PIC16F87/88 family, which introduces nanoWatt technology to the mid-range architecture. It shares core functionality with the PIC16F87 but adds specific analog features like the 7-channel ADC and dual comparators found in the PIC16F88 variant.
