PIC12CE519-04E/P 概要
An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, RAM, program memory (ROM/Flash/OTP), timers, and I/O peripherals on one die. The PIC12CE519 belongs to the PIC10/12/16 mid-range family, which sits in Microchip's hierarchy as: 8-bit PIC -> PIC12 family -> PIC12C5xx sub-family. OTP variants are programmed once via MPLAB PM3 or ICD and cannot be reprogrammed, making them ideal for low-cost high-volume embedded products.
Key features include a powerful 33-instruction RISC architecture with only 35 single-word instructions, an 8-bit timer/counter (TMR0) with 8-bit programmable prescaler, a watchdog timer with its own on-chip RC oscillator for reliable reset, an internal 4MHz RC oscillator (calibrated), and power-saving Sleep mode with Wake-on-I/O-change. The device also integrates an analog comparator and 4-channel 8-bit ADC for sensor interfacing, all in a compact PDIP-8 footprint.
Typical applications include remote control transmitters, sensor nodes, low-end motor control loops, electronic toys and learning kits, battery-powered timers, and small home appliance controllers. The wide extended-temperature rating and 5.5V supply tolerance make it suitable for automotive cabin and industrial sensor applications, where reliable operation in harsh thermal environments is mandatory.
When designing with the PIC12CE519-04E/P, observe the OTP programming voltage timing and ensure the MCLR reset circuit uses a 10k pull-up plus optional diode to VDD. The internal RC oscillator provides +/- 1% accuracy after calibration, but critical timing applications should use an external crystal or resonator. Brown-out detection is not present on this baseline variant - pair it with an external supervisor for industrial 24V-bus designs.

主な用途
PIC12CE519-04E/P の用途: 7 件s: Remote Control Transmitter, Battery-Powered Sensor Node, Low-Cost Electronic Toy Controller, Home Appliance Timer Module, Industrial Sensor Interface Module, Automotive Cabin Accessory Controller, Educational Microcontroller Learning Kit.
Remote Control Transmitter
The PIC12CE519-04E/P's 1.5KB OTP memory and 41-byte RAM are well-suited for infrared or RF remote control transmitters that send fixed command codes. The internal 4MHz calibrated RC oscillator eliminates the need for an external crystal, reducing BOM cost. The 6 GPIO pins directly drive an IR LED driver or low-power RF transmitter stage. Sleep current in the microamp range extends battery life on coin-cell power, while the watchdog timer ensures reliable reset if the firmware hangs.
おすすめ
Battery-Powered Sensor Node
The PIC12CE519-04E/P operates from 3.0V to 5.5V and includes Sleep mode with Wake-on-I/O-change, making it ideal for battery-powered sensor nodes that wake briefly to take a measurement and transmit, then return to deep sleep. The 16-byte EEPROM data area provides non-volatile storage for calibration constants and node IDs. Extended temperature rating (-40C to +125C) supports outdoor and automotive cabin deployments where temperature swings are common.
おすすめ
Low-Cost Electronic Toy Controller
Toy manufacturers benefit from the PIC12CE519-04E/P's OTP programming - the one-time-write memory is cheaper per die than Flash, lowering unit cost in millions-of-units production runs. The PIC12 RISC architecture provides 33 single-word instructions that compile to very compact code, fitting complex sound-and-light toy sequences into 1.5KB. The 8-pin PDIP package is easy to hand-solder or wave-solder on toy PCBs.
おすすめ
Home Appliance Timer Module
The PIC12CE519-04E/P's 8-bit TMR0 timer with programmable prescaler provides accurate timing for kitchen appliances such as microwave ovens, coffee makers, and washing-machine sub-controllers. The integrated watchdog timer with dedicated on-chip RC oscillator protects against code lockups in high-noise motor environments. Extended temperature rating handles the heat inside appliance cabinets. The 6 GPIO pins drive relay drivers, LED indicators, and membrane keypads.
おすすめ
Industrial Sensor Interface Module
The PIC12CE519-04E/P's extended -40C to +125C operating range and 5.5V supply tolerance suit industrial 24V-bus sensor interface modules when paired with external voltage regulation. Its RISC core handles Modbus RTU framing, 4-20mA loop conversion, and digital filtering within the 1.5KB program memory budget. The 16-byte EEPROM stores calibration data and Modbus node addresses. OTP memory prevents accidental firmware corruption in fielded industrial equipment.
おすすめ
Automotive Cabin Accessory Controller
Within automotive cabin environments (where AEC-Q100 Grade 3 temperature -40C to +85C is typical), the PIC12CE519-04E/P can control non-safety accessories such as interior lighting, ambient LED drivers, and seat-heater timers. The extended -40C to +125C rating provides margin against solar loading through windshield glass. The 41-byte RAM supports Modbus or LIN-subset framing for body-electronics communication. OTP memory reduces per-unit cost in high-volume automotive programs.
おすすめ
Educational Microcontroller Learning Kit
Universities and hobbyists use the PIC12CE519-04E/P as a teaching vehicle for the PIC12 RISC architecture. The 8-pin PDIP package fits in standard breadboards and the ICSP interface allows student projects to be programmed in-circuit. The 33-instruction RISC set is small enough to be taught in a single semester. The OTP nature means students cannot 'brick' the part by misprogramming, and replacement parts cost less than $2 each.

設計ノート
The PIC12CE519-04E/P operates from 3.0V to 5.5V VDD. For industrial 24V-bus designs, add a linear regulator (e.g. Microchip MCP1700) plus a 10uF bulk capacitor and 100nF decoupling cap placed within 5mm of the VDD pin. Brown-out detection is not present on this baseline variant; pair it with an external voltage supervisor such as MCP100 or MCP131 if the system must recover gracefully from supply droops.
Place the MCLR pull-up resistor (typically 10k) as close to the MCLR/VPP pin as possible. Add a diode from MCLR to VDD for fast discharge of the MCLR capacitance during power-down. Keep ICSP traces (ICSPCLK on GP1, ICSPDAT on GP0) short and away from high-current switching nodes to prevent programming interference. The OSC1/OSC2 traces should be as short as practical and surrounded by a ground pour to reduce EMI.
Do not attempt to reprogram the PIC12CE519-04E/P - it uses One-Time Programmable memory that cannot be erased. For prototype development, use a Flash-based PIC12F629-I/P or PIC12F675-I/P (same 8-pin PDIP footprint, ICSP-compatible) and only migrate to the CE519 once firmware is finalized. Also note that the 'E' suffix is required for -40C to +125C extended-temperature applications; the non-E variant (PIC12CE519-04/P) is only rated -40C to +85C.
The internal 4MHz calibrated RC oscillator provides +/- 1% accuracy after factory calibration, sufficient for UART baud rates up to 9600 baud and most timer applications. For critical timing such as USB bit-banging, precise baud-rate generation, or RTC accuracy, switch to an external crystal or ceramic resonator on OSC1/OSC2. The Sleep-mode wake-up time from internal RC oscillator is approximately 10us, faster than crystal wake-up (typically 100us).
