PIC16F18323-E/JQ - 8-Bit XLP MCU, 32MHz, 3.5KB Flash | Microchip
The Microchip Technology PIC16F18323-E/JQ is an 8-bit PIC microcontroller in the PIC16F183xx family, featuring a 32MHz internal core, 3.5KB (2K x 14) of Flash program memory, 256 bytes of SRAM, and 256 bytes of EEPROM, housed in a 16-pin UQFN-EP (4x4 mm) package with exposed thermal pad. The device operates from 2.3V to 5.5V and is built on CMOS technology with Microchip's eXtreme Low Power (XLP) architecture.
What is an 8-bit microcontroller? An 8-bit microcontroller (MCU) is a small computer-on-a-chip built around an 8-bit data bus, integrating CPU, RAM, non-volatile program memory (Flash/ROM), EEPROM, and peripherals such as timers, ADC, communication interfaces, and I/O on a single die. 8-bit MCUs sit at the low end of the microcontroller hierarchy (below 16-bit, 32-bit, and Cortex-M class parts) and remain dominant in cost-sensitive, low-power, deterministic-control applications such as consumer appliances, sensor nodes, IoT endpoints, and white goods. PIC microcontrollers use a Harvard architecture with separate program and data buses, optimizing deterministic instruction execution for embedded control.
Key features include Peripheral Pin Select (PPS) for flexible digital peripheral pin mapping, Configurable Logic Cells (CLC), Complementary Waveform Generator (CWG), multiple communication peripherals (UART, SPI, I2C), 10-bit ADC with computation, and the XLP sleep modes that enable sub-µA standby current. The 'E' suffix denotes the -40C to +125C extended operating temperature range, and the 'JQ' suffix denotes the 16-pin UQFN-EP 4x4 mm package.
The 32MHz core provides 8 MIPS of performance with a 4-cycle instruction architecture. The XLP nanoWatt technology achieves typical sleep currents below 50 nA with retention, enabling multi-year battery life in energy-harvesting and coin-cell applications. PPS allows remapping of digital peripherals to any available I/O pin, simplifying PCB layout and enabling peripheral sharing at runtime.
Typical applications include battery-powered IoT sensor nodes, low-power wireless remote controls, smart-home sensor endpoints, wearable health monitors, and white-goods user-interface controllers. The combination of XLP sleep, PPS flexibility, and small UQFN-EP footprint suits compact, energy-constrained designs.
When designing with this device, verify the UQFN-EP exposed-pad PCB land pattern is correctly soldered for thermal dissipation - the pad is the primary heat path. Use MPLAB X IDE with XC8 compiler for code development, and consider the PIC16F18324 for designs that need more memory or I/O in the same UQFN family.
