DEVICE OVERVIEW

The PIC16F18325/18345 devices offer Core Independent Peripherals (CIPs), Intelligent Analog modules, and several other features that allow for high-performance, low-cost, and low-power applications.
The primary differentiating features and specifications of the high-temperature PIC16F18325/18345 devices are:
• Above 125°C, the number of program Flash memory and EEPROM are significantly reduced
• All AC timing specifications are increased by 30% This derating factor includes parameters, such as TPWRT
• Maximum HS frequency of operation is 20 MHz
The test duration for AEC-Q100 reliability testing for devices operating at 150°C is 1,000 hours. Any design operating at 125°C to 150°C for longer than that period is not warranted without prior written approval from Microchip Technology Inc.
