PIC16F18326-E/ST Übersicht
An 8-bit microcontroller (MCU) is a small computer-on-a-chip built around an 8-bit data path, optimized for cost-sensitive embedded control. PIC microcontrollers from Microchip combine a RISC-based CPU core with on-chip Flash, EEPROM, RAM, and a rich set of Core Independent Peripherals (CIPs). Within the broader taxonomy, the PIC16F18326 belongs to the PIC16 family -> 8-bit PIC -> Microcontroller -> Embedded Computing -> Semiconductor.
Key features of the PIC16F18326 include eXtreme Low Power (XLP) technology for sleep currents in the nanoamp range, Peripheral Pin Select (PPS) for flexible digital peripheral routing, a 10-bit ADC, a 5-bit DAC, configurable logic cells (CLC), Complementary Waveform Generator (CWG), and communication peripherals including SPI and I2C. The Functional Safety (FuSa) capability supports IEC 60730 Class B safety requirements in appliance designs.
The PIC16F18326 uses a 14-bit instruction set with hardware stack and interrupt-driven I/O. Its Core Independent Peripherals operate without CPU intervention, freeing the core for power management and housekeeping. PPS remaps digital peripherals to any I/O pin, simplifying PCB layout when signals cross packages or when migrating between PIC16(L)F18326 and PIC16(L)F18346.
Typical applications include IoT sensor nodes, battery-powered wearables, home appliances requiring functional safety, LED lighting controllers, and low-pin-count industrial control. The wide operating voltage range and ultra-low sleep current make it ideal for energy-harvesting designs and remote controls.
When designing with this MCU, leave RA0/RA1 accessible for ICSP programming if in-circuit programming is required. Verify VDD decoupling per the datasheet and respect the absolute maximum ratings, especially for ESD on analog-capable pins exposed to external connectors.

Wichtigste Unterscheidungsmerkmale
- Functional Safety (FuSa) capability for IEC 60730 Class B compliance (vs. PIC16F1829T-I/SO)

Designhinweise
The TSSOP-14 package has an exposed lead pitch of 0.65 mm, requiring careful PCB layout. Per the Microchip datasheet, place a 100 nF decoupling capacitor within 3 mm of the VDD pin (pin 14) and a 10 uF bulk capacitor nearby. If the ICSP interface is used in production, reserve RA0 (ICSPCLK) and RA1 (ICSPDAT) for programming access; add test points or pads to support in-circuit firmware updates without removing the MCU.
Estimated: At 32 MHz active operation from 3.3V supply with all peripherals enabled, the PIC16F18326 draws approximately 2-3 mA per Microchip datasheet typical curves. In sleep mode with Watchdog Timer enabled, current drops to sub-1 uA. For battery-powered designs, duty-cycle the active mode aggressively - the XLP feature combined with sleep-current optimization yields 5+ years on 2xAA cells at 0.1% duty cycle.
When migrating from PIC16F1829T-I/SO to PIC16F18326-E/ST, note the pinout is not drop-in despite both being TSSOP packages - the PIC16F1829 is an 18-pin die mapped to TSSOP-14 with different I/O assignments. Verify pin-by-pin against the datasheet before reusing PCB layouts. Also respect the absolute maximum VDD rating of 5.5V; designs using 5V supplies should add a series resistor or voltage regulator to avoid damage during transients.
PPS (Peripheral Pin Select) allows digital peripherals to be remapped to any digital I/O pin. While this simplifies layout, beware that moving a peripheral away from its default pin can affect timing characteristics on high-speed peripherals. For SPI above 4 MHz or UART above 115200 baud, verify signal integrity on the remapped pin pair. Use the Microchip Pin Manager (MCC) tool to validate assignments before committing to layout.
Compliance-Informationen
RoHS and REACH compliant per Microchip product page. Functional Safety (FuSa) capable supporting IEC 60730 Class B; AEC-Q100 not applicable for this part (not automotive-qualified; automotive variants carry a /VAO suffix). Lead-free termination standard for TSSOP-14 package.
