PIC16C57T-10I/SS 개요
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory, data memory, and programmable I/O peripherals into one package. Within the broader taxonomy, this part belongs to: 8-bit microcontroller -> RISC microcontroller -> embedded controller -> microcontroller unit -> semiconductor IC. PIC16C5X devices implement a Harvard-architecture RISC core with 33 single-cycle instructions and a 12-bit-wide instruction word, delivering roughly 2:1 code compression over competing 8-bit CISC MCUs in its class.
Key features of the PIC16C57T-10I/SS include 8-bit timer/counter resources, a watchdog timer with on-chip RC oscillator, power-on reset, and an internal/external oscillator selection. The OTP EPROM memory allows field programming during prototyping and low-volume production, and the SSOP-28 footprint (5.30 mm body width) makes it suited for space-constrained boards where a PDIP would be too large. The "T" suffix denotes tape-and-reel packaging for high-volume assembly, while the "-10" speed grade specifies the 10 MHz maximum clock.
Typical applications include white-goods and appliance control, automotive body electronics (non-safety), industrial sensor interfaces, simple user-interface panels, and remote-control transmitter logic. The wide operating voltage range and low-power CMOS design also suit battery-powered embedded nodes where deterministic behavior matters more than compute throughput.
When designing with this part, note that OTP memory cannot be re-programmed in-circuit; consider PIC16F equivalents (Flash-based) for design iterations, and budget for an external ICSP header if firmware updates are expected in production.

일반적인 애플리케이션
PIC16C57T-10I/SS 적합 용도: 6 애플리케이션s: White Goods and Appliance Control, Automotive Body Electronics (Non-Safety), Industrial Sensor Interface Nodes, Simple User Interface Panels, Remote Control Transmitter Logic, Battery-Powered Embedded Nodes.
White Goods and Appliance Control
The PIC16C57T-10I/SS fits appliance control boards because its 3 KB OTP EPROM, 20 I/O pins, and 10 MHz RISC core are sufficient for washing-machine, dishwasher, and microwave timing logic. The 8-bit timer/counter drives motor PWM and relay sequencing, while the watchdog timer with on-chip RC oscillator recovers from brown-out events. Industrial -40C to +85C rating handles under-cabinet heat, and the SSOP-28 footprint fits the dense PCB layouts typical of modern appliance mainboards. Designers gain deterministic interrupt latency from the PIC16C5X core, critical for real-time motor control loops.
추천
Automotive Body Electronics (Non-Safety)
Body-electronics modules such as seat controllers, mirror adjusters, and lighting dimmers use the PIC16C57T-10I/SS for low-cost logic. Its industrial temperature range tolerates cabin environments, and the 20 I/O pins drive LEDs, H-bridges, and switch inputs directly. The OTP EPROM provides production-cost advantages over Flash parts in high-volume programs where firmware is finalized. Designers should note this part is not AEC-Q100 qualified; for safety-critical automotive applications, choose PIC16F or PIC18 AEC-Q100 qualified parts instead.
추천
Industrial Sensor Interface Nodes
Sensor-interface modules in industrial settings benefit from the PIC16C57T-10I/SS's deterministic instruction timing and small SSOP-28 footprint. The 8-bit PIC core reads digital sensors, formats data, and drives UART or SPI outputs at rates easily handled by 10 MHz operation. The 72-byte RAM suits simple buffering tasks, and the wide operating voltage range tolerates 24V industrial bus transients. Engineers designing new nodes should consider PIC16F57-I/SS for Flash-based firmware updates when sensor calibration must change between production runs.
추천
Simple User Interface Panels
User-interface panels with button matrices, LED indicators, and 7-segment displays are well served by the PIC16C57T-10I/SS. The 20 I/O pins scan up to 4x4 keypads and drive up to 20 discrete LEDs without external logic, while the 10 MHz core debounces inputs in software with cycle-accurate timing. The PIC16C5X instruction set's compact 12-bit word delivers code density that fits appliance UIs in 3 KB. SSOP-28 mounting keeps the panel PCB small enough for handheld or wall-mounted form factors.
추천
Remote Control Transmitter Logic
RF remote controls and IR transmitter key fobs use the PIC16C57T-10I/SS for low-cost logic that encodes button presses into PWM or PPM streams. The PIC core's 10 MHz capability generates accurate carrier frequencies without external crystals in many designs, and the OTP EPROM secures the encoding algorithm against cloning. The SSOP-28 footprint fits slim key-fob housings, and the low-power CMOS core extends battery life. Designers can use the same silicon across product variants by simply changing the OTP image during production programming.
추천
Battery-Powered Embedded Nodes
Battery-powered wireless sensor nodes and small IoT endpoints benefit from the PIC16C57T-10I/SS's low-power CMOS core and small SSOP-28 package. The wide industrial temperature range supports outdoor deployments, while the deterministic RISC architecture allows tight sleep-mode wake cycles for years of battery life. 72 bytes of RAM suits simple packet buffering, and 20 I/O pins connect to sensors, status LEDs, and low-power radios. For new IoT designs requiring OTA firmware updates, the Flash-based PIC16F57-I/SS in the same footprint is recommended.

설계 노트
The PIC16C57T-10I/SS contains OTP EPROM, not Flash memory. Once programmed, the firmware cannot be erased or rewritten - any bug discovered after programming requires a new device. Budget an external ICSP header and stock pre-programmed parts for engineering bring-up. For prototype and low-volume runs, choose the Flash-based PIC16F57-I/SS in the same SSOP-28 footprint to enable iterative firmware development.
The SSOP-28 package has a 0.65 mm pitch and 5.30 mm body width. Use a 4-layer PCB with continuous ground plane under the MCU to reduce EMI susceptibility. Place the decoupling capacitor (100 nF ceramic + 10 uF bulk) within 5 mm of the VDD pin. Route the OSC1/OSC2 traces symmetrically with ground guard traces if using a crystal oscillator, or keep them short if using an external clock source.
Estimated: at 10 MHz continuous operation with all 20 I/O pins switching, the PIC16C57T-10I/SS consumes approximately 5 mA from 5V. Power dissipation is therefore approximately 25 mW, well within the SSOP-28 thermal envelope (theta_JA ~ 95 C/W). Junction temperature rise above ambient is negligible (<2.4 C), so no special thermal management is required for typical industrial -40C to +85C operation.
