32 MHz 8-bit MCU with 14 KB Flash — active and available
The Microchip PIC16F1847-I/ML is an 8-bit PIC core MCU running at 32 MHz, with 14 KB (8K x 14) Flash program memory, 1K x 8 SRAM, and 256 x 8 EEPROM. The device integrates a 10-bit ADC with 12 channels, multiple serial interfaces (EUSART, I2C, SPI, LINbus, RS-232, RS-485), and peripherals including PWM, brown-out detect, POR, and WDT.
Memory and peripheral fit for control and communication
The 14 KB Flash and 1 KB SRAM support moderate firmware sizes typical for sensor interfaces, motor control loops, and human-machine interface (HMI) panels. The 256-byte EEPROM allows non-volatile storage of calibration or configuration data without external memory. The 12-channel 10-bit ADC covers analog inputs for temperature, pressure, or current sensing. The EUSART and SPI/I2C blocks handle RS-232/485 and LINbus communication, common in industrial automation and automotive aftermarket modules.
28-QFN package with exposed pad — thermal and layout notes
Housed in a 28-VQFN Exposed Pad (6x6 mm body), the PIC16F1847-I/ML provides 15 I/O lines.
This makes it a safe choice for new product introductions and ongoing production runs. The base product number PIC16F1847 covers multiple package and temperature variants, simplifying BOM consolidation.
