PIC16F15355-E/SP - 8-Bit MCU, 14KB Flash, 28-SPDIP | Microchip
MPN: PIC16F15355-E/SP ✓ Hoạt độngPIC16F15355-E/SP Tóm tắt
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program and data memory, peripherals, and I/O on one die. The 8-bit MCU category occupies the lowest-power tier of the embedded computing hierarchy (8-bit -> 16-bit -> 32-bit MCU -> microprocessor -> SoC) and dominates cost-sensitive applications where deterministic real-time behavior outweighs raw throughput. Microchip's enhanced mid-range core adds a 14-bit instruction word and a hardware multiplier, letting one PIC16 family cover most sensor-interface, lighting-control, and small-motor drive tasks previously reserved for 16-bit parts.
Key features include four 10-bit PWM outputs, one comparator, a 5-bit and 10-bit DAC, a 10-bit ADC, a Complementary Waveform Generator (CWG), four Configurable Logic Cells (CLC), two Enhanced USARTs, and SPI / I2C peripherals. Core Independent Peripherals allow logic to be wired in hardware without CPU cycles, reducing active-mode current and enabling sleep-mode event handling. XLP technology delivers typical sleep currents in the nanoamp range, suiting battery and energy-harvesting designs.
Typical applications include low-power IoT sensor nodes, battery-powered home automation, LED lighting controllers, automotive interior accessories, small appliance motor control, and consumer white-goods user interfaces. The 28-SPDIP footprint also makes it well suited to through-hole prototyping, breadboards, and educational platforms where the part can be repeatedly inserted and removed.
When designing with the PIC16F15355-E/SP, reserve one GPIO for an ICD/ICSP header so MPLAB Xpress and PICkit programmers can attach without rework. Always include decoupling capacitors of 100 nF plus 10 uF within 5 mm of VDD, and tie all unused I/O pins to defined logic levels to minimize sleep current. For low-power designs, use the CLC and CWG to keep the CPU in sleep while peripherals continue to operate.

Ứng dụng tiêu biểu
PIC16F15355-E/SP phù hợp cho 6 Áp dụngs: Battery-Powered IoT Sensor Node, Home Automation Lighting Controller, Small Appliance Motor Control, Automotive Interior Accessory Module, Consumer White-Goods User Interface, Educational and Prototyping Platform.
Battery-Powered IoT Sensor Node
The PIC16F15355-E/SP's 14 KB Flash and 1 KB SRAM comfortably run a small RTOS or state-machine loop that polls sensors and transmits over UART or SPI. XLP nanoamp sleep current and the CWG/CLC peripherals let the CPU stay in sleep while timer-gated events wake it for sub-millisecond duty cycles, enabling years of life on a CR2032 coin cell. At 32 MHz the 8 MIPS core can encrypt, filter, and packetize readings before returning to sleep, and the 28-SPDIP package fits hand-held enclosures.

Home Automation Lighting Controller
The PIC16F15355-E/SP drives LED strings via its 4-channel 10-bit PWM and Complementary Waveform Generator, supporting dimming curves, color mixing, and zero-cross detection. The 10-bit ADC samples wall-cycle current for feedback, while the 10-bit DAC generates reference voltages for constant-current driver ICs. Two EUSARTs bridge the lighting bus (DMX or DALI) and a Wi-Fi/BLE module for app control, all inside the 2.3 V to 5.5 V supply range required for AC-line-derived rails.
Được đề xuất
Small Appliance Motor Control
The PIC16F15355-E/SP uses its CWG to generate complementary PWM pairs with programmable dead-band, driving half-bridge MOSFET stages for BLDC, brushed DC, or stepper motors. The on-chip comparator closes the current-control loop without CPU intervention, while the CLCs implement hardware fault interlocks that shut down PWM within microseconds of an overcurrent event. This keeps firmware simple and lets the 8 MIPS core handle user-interface, HMI, and serial diagnostics.
Được đề xuất
Automotive Interior Accessory Module
Automotive interior accessories such as ambient lighting, seat heaters, or window controllers benefit from the PIC16F15355-E/SP -E extended temperature grade (-40 C to +125 C) and 28-SPDIP ease of assembly. The 10-bit ADC multiplexes multiple analog sensors (NTC temperature, current shunt), while EUSARTs handle LIN or UART links to the body controller. For full automotive-grade qualification, Microchip recommends the -VAO suffix parts or PIC18F variants in the same package.
Được đề xuất
Consumer White-Goods User Interface
The PIC16F15355-E/SP drives capacitive touch buttons through the CLC, scans LED indicators via PWM dimming, and reads rotary encoders through EUSARTs - all without a dedicated touch IC. The DAC sets bias points for analog front-ends, while the comparator detects zero-cross events on the AC mains for triac-fired loads. Its 28-SPDIP footprint is breadboard-friendly for early UI prototypes, and the XLP sleep mode means standby power stays below regulatory limits for energy-star appliances.
Được đề xuất
Educational and Prototyping Platform
The PIC16F15355-E/SP in 28-SPDIP is ideal for university embedded courses, hobbyist projects, and breadboard prototypes because the through-hole pins are rugged and reusable. MPLAB X IDE supports the PIC16F15355 with free XC8 compiler and PICkit programmer compatibility, and the 14 KB Flash is large enough to teach interrupt-driven firmware, RTOS basics, and Core Independent Peripheral concepts in a single semester. The same family offers QFN variants when student designs graduate to SMT.

Ghi chú thiết kế
Place a 100 nF ceramic decoupling capacitor within 5 mm of the VDD pin and a bulk 10 uF capacitor on the same rail as close as practical. Tie all unused GPIO to defined logic levels (either VDD through a 10 kohm resistor or VSS) to prevent floating-input current draw. For battery-powered designs, enable the FVR (Fixed Voltage Reference) only during ADC measurements and disable it during sleep to minimize quiescent current.
Keep the crystal traces (OSC1/OSC2) short and shield them with a ground pour to reduce EMI coupling into the RF-sensitive CLC and CWG outputs. Route the MCLR/VPP line away from PWM outputs to avoid reset glitches during high-side switching. For SPDIP layouts, leave a 0.1 inch hole pattern for an ICSP header so a PICkit can be attached without rework during development.
Do not enable the weak pull-ups on RB0 (which doubles as the CWG output) without considering the impact on PWM drive strength - the weak pull-up can fight external drivers. Avoid using CLC outputs as direct high-current loads; CLCs are logic peripherals, not drivers. When migrating from PIC16F1516 to PIC16F15355, recompile all C code because the CLC and CWG register maps differ between families.
When using the SPI or I2C peripherals, add 4.7 kohm pull-ups on SCL/SDA lines and keep bus traces under 50 mm to maintain signal integrity at 400 kHz I2C fast-mode. For SPI runs above 100 mm, add a series 33 ohm resistor near the master to dampen reflections. Use the EUSART in 16x baud mode for cleaner UART sampling on long cables.
Estimated: at maximum CPU activity (8 MIPS, 3.3 V VDD), the PIC16F15355-E/SP typically draws around 3 mA, so power dissipation is roughly 10 mW, well within SPDIP thermal limits (theta_JA near 70 C/W). At 5.5 V VDD the active current rises to about 5 mA, or ~28 mW dissipation. No heatsink or thermal management is required for the 28-SPDIP package in normal embedded use; this is an estimate, not a datasheet specification.
