PIC16F1828-I/P - 7KB Flash 8-Bit MCU 20-PDIP | Microchip
The Microchip Technology PIC16F1828-I/P is an 8-bit PIC microcontroller built on the enhanced mid-range core with 49 instructions, 16-level deep hardware stack, and 32 MHz internal oscillator, housed in a 20-pin PDIP (through-hole) package. The part integrates 7 KB Flash program memory (4K x 14 words), 256 bytes RAM, and 256 bytes EEPROM, while operating from 1.8 V to 5.5 V across the -40 °C to +85 °C industrial temperature range.
An MCU (microcontroller unit) is a single-chip computer that integrates a CPU core, non-volatile program memory, working RAM, and a range of digital/analog peripherals. The PIC16F1828 belongs to the PIC16 family of 8-bit microcontrollers from Microchip, which sits below the PIC18/dsPIC/PIC32 product tiers and uses a RISC-style modified Harvard architecture. Within the broader taxonomy, microcontrollers are classified as integrated circuits within the embedded computing category, alongside MCUs from competing architectures such as ARM Cortex-M0+ (e.g., STM32G0, ATSAM), AVR (ATmega), and 8051. Designers choose 8-bit PIC MCUs when low cost, ultra-low power (XLP nanoWatt technology), deterministic interrupt handling, and broad toolchain/middleware support outweigh raw MIPS.
Key features of the PIC16F1828 include the integrated mTouch capacitive sensing module, a Data Signal Modulator (DSM) for generating custom bit streams, a 5-bit DAC reference (CVREF), MI2C/SPI/EUSART with auto-baud, two Enhanced CCP and two standard CCP PWM modules, selectable voltage-reference comparators, and on-chip debug support without requiring a debug header. The device delivers nanoWatt XLP sleep currents typically below 50 nA, enabling years of operation from a coin cell. NFC access to AGD and ECG ECG AFE integration combined with high-fidelity signal chain interfaces support both battery-powered sensor nodes and line-powered human-interface designs.
Architecturally, the PIC16F1828 uses a 14-bit instruction word, two-stage pipeline, and a peripheral pin-select (PPS) engine that remaps digital functions onto a wide set of I/O pins. The device supports in-circuit serial programming (ICSP) via two pins and offers an optional external debug header (AC244043) for use with PICkit 3 or MPLAB ICD 3. Its 12 I/O blocks (I/O Ports: 12 per data brief) and 8-channel 10-bit ADC make the part suitable for mixed analog/digital signal acquisition.
Typical applications include consumer remote controls (PIR + capacitive touch keypads), battery-powered IoT sensor nodes, LED lighting controllers with PWM dimming, HVAC thermostat front-ends, low-cost motor control for small DC fans and pumps, and industrial control replacement signals requiring UART/SPI/I2C connectivity. Designers pick this part when cost, footprint, and ultra-low standby current dominate over compute throughput.
When designing with the PIC16F1828-I/P, route VDD and VSS with wide, short traces to a 100 nF bypass capacitor placed within 5 mm of the package pins, and add a 10 µF bulk capacitor at the board supply entry. The through-hole PDIP package supports hand-soldered prototypes and is designed to be soldered with standard wave-soldering or hand-soldering equipment. Always honor the absolute maximum ratings of 6.5 V on VDD to avoid latch-up.
