PIC16F15223T-I/ST 概述
An 8-bit microcontroller is a small computing-on-a-chip based on a CPU with an 8-bit data bus width, optimized for embedded control tasks. Within the broader taxonomy, this part belongs to the 8-bit MCU category, which descends from microcontroller, embedded controller, integrated circuit, and finally semiconductor. PIC16F152xx family parts sit below the PIC16 family umbrella and combine deterministic real-time control with low-power eXtreme Low-Power (XLP) Sleep modes well below 1 uA, suiting battery-backed and energy-harvesting designs.
Key features include 49 base instructions, 16 stack levels, self-read/write Flash, a hardware Limit Timer (HLT), a Watchdog Timer (WDT), and Functional Safety (FuSa) documentation that simplifies IEC 61508 SIL-2 designs. The TSSOP-14 footprint delivers 12 available I/O pins after power and ground assignment, with PPS routing remapping digital peripherals to a wide set of pins. Operating voltage spans 1.8 V to 5.5 V across -40 C to +85 C industrial temperature.
Architecturally, the device uses the enhanced mid-range PIC core with a 14-bit instruction word, providing deterministic interrupt latency and a single-cycle instruction execution at the system clock. The CIP blocks such as the Hardware Limit Timer and Configurable Logic Cell (CLC) let designers offload sequencing from the CPU, freeing bandwidth for application code while keeping the BOM small.
Typical applications include sensor signal conditioning, low-cost motor and solenoid drivers, white-goods and appliance user-interface controllers, and IoT edge-node data acquisition. The wide voltage range also accommodates 3.3 V and 5 V mixed-signal boards common in industrial automation. A consideration when designing with this device is the 3.5 KB Flash ceiling; code-heavy applications should evaluate PIC16F15244/15245 family members in the same TSSOP-14 footprint. This page synthesizes distributor pricing, drop-in package-compatible alternatives, and practical design notes not consolidated in the manufacturer datasheet alone.

典型应用
PIC16F15223T-I/ST 适用于 6 应用s: Battery-Backed IoT Sensor Node, Appliance User Interface Controller, DC Fan / Solenoid PWM Driver, Sensor Signal Conditioning Front-End, White Goods Cost-Down Board, Functional Safety Subsystem (SIL-2).
Battery-Backed IoT Sensor Node
The PIC16F15223T-I/ST suits battery-backed IoT sensor nodes because its eXtreme Low Power (XLP) Sleep mode drops quiescent current below 1 uA, enabling multi-year coin-cell life. The 10-bit ADC with PPS-mappable inputs reads temperature, optical, or occupancy sensors while the MCU idles between wake events. The 32 MHz core wakes fast enough to burst-transmit over EUSART or SPI within milliseconds, minimizing energy per cycle.
推荐
Appliance User Interface Controller
The PIC16F15223T-I/ST handles user-interface scanning in washing machines, dishwashers, and microwave ovens where deterministic response matters. Two PWM channels drive LED backlights or buzzer tones, while two CCP peripherals debounce and time key-matrix scans. Peripheral Pin Select frees the board designer to remap any digital function to any GPIO, simplifying PCB routing around displays and connectors.
推荐
DC Fan / Solenoid PWM Driver
For low-cost 12 V or 24 V brushed DC fan and solenoid control, the PIC16F15223T-I/ST provides two PWM channels that generate complementary or independent duty cycles at up to 32 MHz system clock. The Hardware Limit Timer (HLT) clamps minimum on/off times in firmware-free hardware, protecting solenoids from inductive kickback. Wide 1.8 V-5.5 V operation supports both 3.3 V logic and direct 5 V power stages.
推荐
Sensor Signal Conditioning Front-End
In factory automation, the PIC16F15223T-I/ST serves as a front-end MCU for 4-20 mA loop sensors, thermistor bridges, or strain-gauge amplifiers. The 10-bit ADC digitizes conditioned signals, MSSP delivers SPI or I2C to backplane MCUs, and the EUSART streams diagnostics. Industrial -40 C to +85 C rating supports cabinet and outdoor enclosures with no extra derating.
推荐
White Goods Cost-Down Board
Price-sensitive white-goods designs (rice cookers, air purifiers, basic washing machines) target minimal BOM cost while preserving reliability. The PIC16F15223T-I/ST integrates timers, ADC, and CIP logic, replacing multiple analog timers and logic ICs. The 14-TSSOP footprint keeps the PCB small, and XLP Sleep meets standby regulations without an external RTC chip.
推荐
Functional Safety Subsystem (SIL-2)
For IEC 61508 SIL-2 systems the PIC16F15223T-I/ST is documented as Functional Safety (FuSa) capable per Microchip's family safety manual, enabling developers to certify end products without separate FMEDA re-spins. The Watchdog Timer, HLT, and CRC-accelerated CIP blocks support self-test routines. Designers retain the 14-TSSOP footprint, easing PCB reuse across safety-rated and non-rated variants.

设计说明
Estimated: at VDD=3.3 V and CPU idle in XLP Sleep, the PIC16F15223T-I/ST draws under 1 uA. With 32 MHz active core, expect ~3-5 mA. Place a 100 nF ceramic decoupling capacitor within 3 mm of the VDD pin and a bulk 10 uF on the supply rail; this minimizes ADC rail noise that would otherwise couple into low-level sensor reads.
Estimated: TSSOP-14 theta_JA is approximately 100 C/W on a standard 4-layer JEDEC test board, so at 5 mA and 5 V the die dissipates about 25 mW, giving a junction rise of only 2.5 C above ambient. No thermal management is required even in sealed enclosures under normal conditions.
Keep the ICSP clock/data traces short and add a 4.7 kohm pull-up on MCLR to VDD for in-circuit serial programming reliability. Place the ICSP header on the board edge for probe access. Use a guard trace around the ADC input traces and route them away from PWM outputs to avoid digital switching noise coupling into analog conversions.
Do not assume any pin is 5 V tolerant - the absolute maximum on any I/O is VDD + 0.3 V. Configure unused pins as outputs (low) rather than inputs to avoid floating CMOS input current. When migrating from PIC16F1xxx older families, double-check the PPS mapping table because not all peripherals map identically to the same physical pins.
合规信息
