PIC16F1828-E/GZ Overview
An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory (Flash/ROM), volatile data memory (RAM), and peripheral set on one die. PIC16F series microcontrollers sit in the mid-range enhanced PIC family hierarchy: 8-bit CPU -> PIC16 enhanced mid-range -> PIC16F182x sub-family -> PIC microcontrollers -> Microchip 8-bit portfolio -> embedded MCU. The XLP (eXtreme Low Power) branding reflects active power-management features such as ultra-low sleep current and multiple idle modes that suit battery-powered and energy-harvesting designs.
Key features include 12-channel 10-bit ADC, two 8-bit timers and one 16-bit timer, enhanced PWM with complementary outputs, configurable logic cell (CLC), and multiple serial interfaces (EUSART, MSSP for I2C/SPI). The integrated mTouch™ peripheral enables capacitive touch button, slider, and proximity sensing without external components, reducing BOM cost. On-chip debug via ICSP eliminates the need for an external debug header for in-circuit development with PICkit™ 3 or MPLAB® ICD 3.
Architecturally the PIC16F1828 uses Microchip's 14-bit instruction word RISC core with 200ns instruction execution at 20MHz (32MHz max), 16-level hardware stack, and 32 interrupt sources. On-chip peripherals are mapped via the peripheral pin select (PPS) system, allowing flexible digital function routing to most I/O pins. The 4x4 mm 20-UQFN package has an exposed thermal pad and operates in -40C to +125C extended industrial/automotive temperature range for harsh-environment applications.
Typical applications include capacitive touch user interfaces for appliances, IoT sensor nodes with multi-year battery life, small home appliances and white goods, LED lighting controllers with dimming, and automotive body controllers. The combination of low-power sleep modes, integrated touch sensing, and tiny 4x4 mm QFN footprint suits space- and cost-sensitive designs.
When designing with this device, configure PPS mappings carefully because peripheral-to-pin remapping differs between PIC16F1828 package variants (UQFN vs SOIC/SSOP). For capacitive touch, follow Microchip application note AN1478 for sensor layout and tuning. Always bypass VDD with a 0.1uF ceramic capacitor and tie all unused I/O pins to defined logic states to minimize current draw in sleep mode.

Key Differentiators
- Integrated mTouch capacitive touch peripheral with 12 channels (vs PIC16F1829-I/ML)
- Smallest UQFN-20 4x4 mm footprint in PIC16F182x family (vs PIC16F1828-E/ML)
- Extended -40C to +125C temperature range (vs PIC16F1828-I/GZ)
- Active production lifecycle status (vs PIC16F1768-I/ML)
Design Notes
Place a 0.1uF ceramic decoupling capacitor as close as possible to the VDD pin (pin 14) of the PIC16F1828-E/GZ, with the ground side connected to VSS (pin 10) using a wide short trace. For the UQFN-20 (4x4 mm) package, solder the exposed thermal pad (pin 21 / EP) to a ground copper pour of at least 10x10 mm with multiple thermal vias to the inner ground plane for heat dissipation. Keep sensitive analog traces (ADC inputs) away from PWM and digital switching signals to minimize crosstalk into the 10-bit ADC measurements.
The PIC16F1828-E/GZ supports sleep current below 20 nA typical (per datasheet 41439A), but total quiescent draw is dominated by peripherals left enabled. Configure all unused peripherals to OFF state via PMDx registers and set unused I/O pins as outputs driving low (not floating) before entering SLEEP to achieve datasheet-specified nanoWatt XLP sleep current. For battery-powered designs, use the on-chip LFINTOSC (31 kHz) during sleep and switch to HFINTOSC only when active processing is required.
Do not confuse the PIC16F1828 pinout across package variants - UQFN-20 (4x4 mm, E/GZ), QFN-20 (6x6 mm, E/ML), and SOIC-20 have different pin assignments for peripheral functions even though pin count matches. Always re-validate pin mapping when switching between PIC16F1828-E/GZ and PIC16F1828-E/ML or PIC16F1828-I/ML. Also note that PIC16F1828 differs from PIC16F1824 in memory map - PIC16F1828 has 7KB Flash while PIC16F1824 has 4KB Flash, so code compiled for one will not run on the other without recompiling.
For capacitive touch mTouch sensor PCB layout, follow Microchip application note AN1478 guidelines: route touch sensor traces with 7-10 mil trace width on a dedicated inner layer or top layer with minimum 0.5 mm clearance to adjacent traces, avoid ground pour under touch electrodes, and place a hatched ground hatch around but not under the touch sensor. The 4x4 mm UQFN-20 footprint allows the entire touch panel to fit on a small daughter board, but maintain a minimum 4 mm clearance between touch sensors and noisy PWM/LED driver traces.
Compliance Information
RoHS compliant per Microchip product page. Standard E/GZ grade is not AEC-Q100 qualified; automotive designs requiring AEC-Q100 should select the -VAO variant. Lead-free / matte-tin finish standard.
