PIC16F18875-E/MV - 8-Bit MCU 32MHz 14KB Flash 40-UQFN | Microchip
MPN: PIC16F18875-E/MV ✓ Hoạt độngPIC16F18875-E/MV Tóm tắt
An 8-bit microcontroller (MCU) is a single-chip processor whose data path is 8 bits wide, optimized for low-cost, low-power, and deterministic control tasks. The 8-bit MCU hierarchy sits beneath the broader semiconductor and embedded processor taxonomy, and the PIC16F18875 belongs to Microchip's enhanced mid-range PIC16 core family, offering richer peripherals than legacy PIC16F parts while preserving the familiar instruction set. This positions the part between simple 8-bit controllers and 32-bit ARM Cortex-M devices, balancing code density, ease of use, and peripheral integration.
Communication peripherals include EUSART with LIN support, SPI, and I2C, while power management features eXtreme Low Power (XLP) technology with IDLE and DOZE modes plus Peripheral Module Disable (PMD) for fine-grained current control. Functional Safety (FuSa) features simplify IEC 60730 Class B compliance for appliance and industrial designs, making this MCU well-suited for safety-critical and regulated end products.
The 40-UQFN package provides 36 I/O pins across multiple ports with PPS remapping, allowing designers to assign digital peripherals to almost any pin for simplified PCB routing. The exposed thermal pad improves power dissipation for sustained MIPS operation. Typical applications include consumer appliances, industrial sensor interfaces, IoT edge nodes, lighting controls, motor control loops, and battery-powered portable devices where low sleep current and rich analog peripherals reduce BOM cost.
When designing with this device, allocate budget for the ICD 3 or PICkit 4 programming/debug header and ensure the 5x5 mm UQFN land pattern uses NSMD pads with via-in-pad for the thermal pad to maximize heat sinking. The PPS system must be configured before peripheral use, so allow extra code space and runtime for the configuration lock.

Bảo phân biệt quan trọng
- Functional Safety (FuSa) IEC 60730 Class B support (vsPIC16F18854-E/MV)
- 40-UQFN (5x5) package option preserves more I/O than 28-pin siblings (vsPIC16F18855-I/MV)
- Peripheral Pin Select (PPS) on all digital peripherals (vsLegacy PIC16F877A)
Ghi chú thiết kế
The 40-UQFN (5x5) package has an exposed thermal pad that must be soldered to a 5x5 mm copper pad with via-in-pad stitching to maximize heat dissipation. Use Non-Solder Mask Defined (NSMD) land patterns with 0.2 mm pad pitch and 0.4 mm via diameter. Place decoupling capacitors (100 nF + 1 uF) within 2 mm of VDD/VSS pins to minimize switching noise on 32 MHz core transitions.
Enable the on-board Voltage Regulator (VCAP) and place a 1 uF ceramic capacitor at the VCAP pin (RA5) when using the device without an external regulator. For battery applications, leverage the XLP sleep mode with Watchdog Timer (WDT) wake-up for currents below 1 uA typical. Always ramp VDD monotonically and respect the minimum rise-time specification to avoid malfunction during power-on.
Always configure Peripheral Pin Select (PPS) before enabling peripherals; PPS registers are unlocked after a reset and must be written with the unlock sequence (PPSLOCKED bit). Unused I/O pins should be configured as outputs low or inputs with internal pull-ups to minimize power consumption and avoid floating inputs. The ICD 3 / PICkit 4 debugger must connect to RB6 (PGC) and RB7 (PGD) - reserve these pins or remap debug via PPS only with caution.
