PIC16F753T-I/ST - 8-Bit MCU, 3.5KB Flash, 14-TSSOP | Microchip
MPN: PIC16F753T-I/ST ✓ Hoạt độngPIC16F753T-I/ST Tóm tắt
A microcontroller (MCU) is a single-chip computer containing a CPU, non-volatile program memory (Flash), working RAM, and a range of peripheral IP blocks such as ADC, timers, comparators, and communication peripherals. The PIC16F753 belongs to Microchip's PIC® 16F sub-family positioned between 8-pin baseline parts and higher-pin PIC18/dsPIC parts, used widely in cost-sensitive consumer, appliance, lighting, and industrial sensor applications where minimal BOM and on-chip analog integration matter more than absolute compute throughput.
Key integrated peripherals include one operational amplifier, two high-speed analog comparators (50 ns propagation delay), one Capture/Compare/PWM (ECCP) module, an 8-channel 10-bit ADC with internal voltage reference, one dual-range 9-bit DAC, an internal 8 MHz oscillator, and support for an external 32 kHz secondary oscillator. Brown-out Reset (BOR), Power-On Reset (POR), a Watchdog Timer (WDT) with its own on-chip low-power oscillator, and an In-Circuit Serial Programming (ICSP) interface are also provided.
The architecture is based on a 14-bit instruction word with a hardware stack and an interrupt controller; the enhanced mid-range core adds hardware-context save on interrupt entry/exit, reducing ISR overhead. The internal 8 MHz oscillator is factory calibrated and paired with a Phase-Locked Loop giving selectable 8/16/32/500 kHz LF operating modes for low-power sleep operation, allowing the designer to trade throughput against quiescent current.
Typical applications include LED lighting drivers, battery chargers, sensor signal conditioning, small BLDC/PWM motor control loops, and white-goods user interface boards. The internal op-amp and comparators remove the need for external analog front-ends, while the 9-bit DAC allows slope compensation in switch-mode and Li-ion charging topologies without external references.
When designing with this part, choose decoupling per Microchip AN576 (one 100 nF plus one bulk cap per VDD pin) and respect the 14-pin TSSOP's 1.0 mm pitch reflow profile to avoid tombstoning during reflow. If a 20-pin variant is preferred for additional I/O, the PIC16F767/777 family drops in with the same peripheral set.

Ứng dụng tiêu biểu
PIC16F753T-I/ST phù hợp cho 7 Áp dụngs: LED Lighting Drivers, Battery Charger / Fuel-Gauge Front-End, Sensor Signal Conditioning, Small BLDC / Fan Motor PWM Control, White Goods / User Interface Boards, Industrial Sensor / Process Controller, Consumer Remote Control / IR Emitter.
LED Lighting Drivers
The PIC16F753T-I/ST is well-suited for LED lighting drivers because its integrated 10-bit ADC, on-chip op-amp, and Enhanced CCP (ECCP) PWM module eliminate external driver ICs. The 9-bit dual-range DAC enables closed-loop current control via analog peak-current-mode regulation, while the 32 kHz LF oscillator reduces standby consumption below 1 uA for ENERGY STAR-compliant standby. With 3.5 KB Flash and 128 B RAM, it handles color-mixing firmware and DMX or 0-10 V dimming inputs in a single 14-TSSOP device.

Battery Charger / Fuel-Gauge Front-End
For Lithium-ion and NiMH charger designs, the PIC16F753T-I/ST integrates the two high-speed comparators (50 ns) needed for slope compensation and current-sense peak detection, plus the 9-bit DAC that sets the charge-current reference. The internal 8 MHz oscillator with PLL supports accurate ADC sampling of battery voltage and current at 20 MHz CPU speed. Its -40C to +85C industrial range covers the thermal envelope of sealed charger bays.
Được đề xuất
Sensor Signal Conditioning
The PIC16F753T-I/ST replaces a discrete analog front-end (op-amp + comparator + MCU) by integrating one on-chip op-amp, two high-speed comparators, an 8-channel 10-bit ADC, and a 9-bit DAC. Thermocouple, thermistor, photodiode, and strain-gauge signal conditioning is feasible with the on-chip op-amp providing reference-scaled gain before the ADC. The 3.5 KB Flash holds calibration tables while the 128 B RAM provides working space for moving-average filtering.

Small BLDC / Fan Motor PWM Control
The PIC16F753T-I/ST's Enhanced CCP (ECCP) module with complementary PWM outputs drives half-bridge and full-bridge low-voltage motor drivers for small BLDC fans, pumps, and stepper coils. Hardware shutdown on overcurrent events uses one of the 50 ns comparators referenced to a sense resistor; the other comparator can be reused as BEMF zero-cross detection for sensorless trapezoidal commutation. At 20 MHz instruction rate, the firmware control loop has 200 ns tick resolution.

White Goods / User Interface Boards
In washing machines, dishwashers, and ovens, the PIC16F753T-I/ST serves as a keypad/LED driver slave MCU taking the load off a larger host CPU. The 9-bit DAC and 10-bit ADC digitize rotary-knob positions and temperature probes, while the ECCP generates tone/sounder drives. With industrial-grade -40C to +85C operation and a 14-TSSOP package, it fits behind the control panel with standard reflow profile and supports ICSP over a 5-pin header for production line programming.
Được đề xuất
Industrial Sensor / Process Controller
The PIC16F753T-I/ST provides a small-footprint control node for industrial 4-20 mA loops and discrete-binary sensor aggregators. Its 2.0-5.5 V supply range accepts 24 V industrial rails with a simple LDO pre-regulator, and its comparators act as threshold detectors for fast signal edges without software polling. With BOR, POR, and a dedicated Watchdog Timer on its own low-power oscillator, the part meets typical IEC 61010 industrial reliability requirements for a 14-pin TSSOP decentralized controller.
Được đề xuất
Consumer Remote Control / IR Emitter
The PIC16F753T-I/ST can drive an IR LED via its ECCP PWM with carrier frequency up to 20 MHz CPU clock driving precise 38 kHz modulation. The internal 8 MHz oscillator with PLL maintains stable timing during 2.0-5.5 V battery droop, and the 9-bit DAC provides intensity control for bidirectional IR or as a temperature reference for the internal sensor. Low-power 32 kHz LF mode extends coin-cell life in remote controls.

Ghi chú thiết kế
Per Microchip application note AN576 (Decoupling and PCB Layout for PICmicro MCUs), place a 100 nF X7R ceramic decoupling capacitor as close as possible to the VDD pin with the trace going to the IC directly (no via between pad and capacitor). Add a 1-10 uF bulk tantalum or ceramic cap on the same power rail to source switching transients from the ECCP PWM and internal ADC reference. The 14-TSSOP 1.0 mm pitch requires standard reflow profile (per IPC JEDEC J-STD-020), but layout the package with 0.4 mm-wide traces to avoid solder bridging.
The PIC16F753T-I/ST has NO true Data EEPROM according to the PIC16F753 datasheet; for non-volatile storage of calibration or running values, use the Flash self-write feature with row-erase discipline and apply wear-leveling in firmware. Mishandling MCLR (RA3 pin) as plain I/O without proper in-circuit programming access can brick the part - always provide a guarded ICSP header (5-pin: VPP, VDD, VSS, ICSPCLK, ICSPDAT) on prototype boards or a guarded test pad on production boards.
The integrated 8 MHz HFINTOSC is factory calibrated; for applications needing accurate RS-232 baud rates or PWM frequency stability, switch to an external 20 MHz crystal on RA6/RA7 (OSC2/OSC1). Estimated: with all peripherals enabled the typical active current consumption is below 2 mA at 5 V and 20 MHz, while LFINTOSC sleep with WDT off can fall below 1 uA - always verify against the data sheet's Electrical Characteristics table for your specific code execution profile.
When using the on-chip op-amp or comparator inputs as analog signals, keep digital traces at least 5 mm away on the same layer and stitch a ground guard ring around sensitive analog nodes to reduce noise coupling from RA5/MCLR digital transitions. The internal voltage reference is shared with the 10-bit ADC and 9-bit DAC - if high-precision measurements are required, buffer the reference at the VREF pin with a low-impedance external op-amp follower (e.g., MCP6001) and avoid switching high-current loads during ADC conversion windows.
