PIC16LF1825-I/SL - 8-Bit 32MHz 14KB Flash MCU | Microchip
MPN: PIC16LF1825-I/SL ✓ Hoạt độngPIC16LF1825-I/SL Tóm tắt
Key features include 12 I/O pins, a 10-bit ADC with up to 11 channels, multiple PWM modules, EUSART, MSSP (SPI/I2C), timers, and a wide operating voltage range of 1.8V to 3.6V. The device supports on-chip debug via Microchip's PICkit and ICD toolchains, eliminating the need for an external debug header on F devices (this LF part requires an external header such as AC244044). The 14-SOIC footprint is compatible with the industry-standard SOIC-14 land pattern, simplifying PCB layout reuse across the PIC16LF18xx family.
The PIC16LF1825 belongs to Microchip's PIC XLP nanoWatt family of 8-bit flash microcontrollers, which targets low-power embedded designs. In this hierarchy it sits as a PIC16 enhanced mid-range core, which provides 49 instructions, a hardware multiplier for efficiency, and an interrupt controller supporting vectored and non-vectored sources. Compared with older baseline PIC16C parts, the enhanced mid-range architecture delivers up to 50% better performance per MHz and is C-friendly through Microchip's XC8 compiler.
Typical applications include consumer touch-button interfaces, portable sensor hubs, low-power remote controls, and simple IoT edge nodes. The 14KB flash accommodates moderate protocol stacks such as Bluetooth Low Energy radio control via a separate transceiver or wired sensor front-ends.
When designing with the PIC16LF1825-I/SL, ensure the LF toolchain variants (PICkit 3, MPLAB X IDE with XC8) are used and that the supply decoupling follows the manufacturer datasheet recommendations. For automotive or AEC-Q100 needs, select the PIC16LF1825-I/SL variant with E-grade temperature range; the standard I-grade part is industrial -40C to +85C.

Ứng dụng tiêu biểu
PIC16LF1825-I/SL phù hợp cho 6 Áp dụngs: Capacitive Touch Button Interface, Portable Sensor Data Logger, Wireless Remote Control (Sub-GHz), Industrial Sensor Hub, IoT Edge Node with BLE HCI, Consumer Appliance Control Board.
Capacitive Touch Button Interface
The PIC16LF1825-I/SL suits capacitive touch buttons thanks to its integrated mTouch CVD peripheral and nanoWatt XLP sleep modes. The 10-bit ADC and on-chip CVD eliminate external touch ICs, simplifying the BOM. Sleep current under 30 nA keeps battery CR2032 coin-cell designs running for years, while 14 KB Flash supports capacitive-state FSM plus a UART bootloader.

Portable Sensor Data Logger
For low-power portable sensor logging, the PIC16LF1825-I/SL offers a 10-bit ADC, 1 KB SRAM, and deep-sleep modes under 30 nA, enabling multi-year battery life on 2x AA cells. The 14 KB Flash accommodates simple FAT-style file records or SD-card SPI handlers, while the 32 MHz core keeps ADC conversions fast and energy-efficient for duty-cycled sensing.

Wireless Remote Control (Sub-GHz)
The PIC16LF1825-I/SL is widely used as the host MCU for sub-GHz transmitters in remote controls. Its low sleep current extends coin-cell battery life, while SPI MSSP directly drives popular sub-GHz radios like the Microchip MRF89XA or Texas Instruments CC1101. The 14 KB Flash handles button-remap tables, wake-up scheduling, and rolling-code security primitives.

Industrial Sensor Hub
For factory sensor nodes, the PIC16LF1825-I/SL provides EUSART and MSSP (SPI/I2C) connectivity, plus 12 GPIO for digital and analog sensor interfacing. The wide 1.8 V to 3.6 V supply and -40 C to +85 C industrial temperature range match industrial node requirements. Its small 14-SOIC footprint fits space-constrained inline sensor enclosures.

IoT Edge Node with BLE HCI
The PIC16LF1825-I/SL can serve as a low-cost BLE HCI host to an external module like the Microchip RN4871 or RN4020. UART EUSART carries the HCI command stream, while sleep modes minimize standby power. 14 KB Flash is ample for BLE GATT state machine plus application-level logic such as sensor drivers and OTA staging.

Consumer Appliance Control Board
In consumer appliances such as coffee makers or air purifiers, the PIC16LF1825-I/SL drives PWM-controlled motors, reads user input via ADC, and communicates with sensors via I2C. Its 1 KB SRAM and 14 KB Flash support state machines for brew cycles or fan curves. The nanoWatt XLP sleep minimizes standby power to meet energy-rating regulations.

Ghi chú thiết kế
Estimated: at 32 MHz, VDDCORE ~3.3 V, VDDIO = 3.3 V, the PIC16LF1825-I/SL active current is approximately 6 mA, giving about 20 mW dissipation. Decouple VDD with a 100 nF X7R ceramic placed within 5 mm of the VDD pin, plus a bulk 1 uF to 10 uF tantalum or ceramic, to keep ripple under 50 mVpp under ADC sampling bursts.
Estimated: at 32 MHz with all peripherals active the device dissipates < 25 mW, well below the 14-SOIC's thermal limit of ~ 750 mW at 25 C ambient. The 14-SOIC (SL) theta_JA is approximately 90 C/W, so no heatsink is needed even in 85 C ambient enclosures.
Route the crystal traces (OSC1/OSC2) short and symmetric with a guard ground on the same layer, and place the mTouch sensor traces no closer than 2 mm to switching power traces to avoid capacitive coupling. The 14-SOIC pin pitch of 1.27 mm allows a 4-layer PCB with stitched grounds to keep analog and digital return paths separated.
Do not swap PIC16LF parts with PIC16F parts in 5 V rails - exceeding 3.6 V on LF parts can damage the silicon. When migrating from PIC16F1825-I/SL to PIC16LF1825-I/SL, ensure no GPIO is exposed to 5 V through pull-ups or external busses; add series resistors or level shifters if necessary.
