20 MHz 8-bit PIC with integrated LCD segment drive
It packs 7 KB of Flash program memory, 256 bytes of RAM, and 256 bytes of EEPROM in a 28-pin SPDIP through-hole package. The standout feature for this class is the integrated LCD driver peripheral, which can directly drive a glass LCD segment display without an external controller IC — a real BOM consolidator for panel-meter, thermostat, and appliance user-interface designs.
7 KB Flash, 256-byte data memory budget
With 7 KB of program Flash and 256 bytes each of RAM and EEPROM, this part fits firmware loads that are moderate by 8-bit standards — think state-machine control loops, sensor polling, and simple communication stacks. The 256-byte RAM ceiling means the firmware engineer should plan for register-based variables and avoid large buffers; a 64-byte UART FIFO would consume a quarter of the available RAM.
Industrial temperature range and wide supply tolerance
The supply voltage range of 2V to 5.5V lets it run directly from a 3.3V regulated rail or a 5V legacy bus, and the 2V floor supports battery-powered operation down to near-depletion. The through-hole 28-DIP package (0.300" width) is a prototyping-friendly footprint that also holds up better in high-vibration environments than a fine-pitch SMT part — a consideration for motor-drive or pump controller boards.
Peripheral set: LCD, 5-channel 10-bit ADC, serial interfaces
Brown-out detect and power-on reset are built in, reducing external supervisor IC count. The 24 available I/O lines on a 28-pin package give reasonable headroom for a mix of digital sensors, pushbuttons, and indicator LEDs alongside the serial buses.
Microchip lists the PIC16F913-I/SP as an Active product with ROHS3 compliance. The base product number PIC16F913 covers multiple temperature and package variants; the -I/SP suffix specifically denotes the industrial temperature grade in the 28-SPDIP package.
