PIC12CE519-04/SM - 8-Bit 4MHz OTP MCU with EEPROM | Microchip
MPN: PIC12CE519-04/SM ✓ Hoạt độngPIC12CE519-04/SM Tóm tắt
An 8-bit microcontroller (MCU) is a small computer-on-a-chip that combines a CPU, RAM, non-volatile program memory, and I/O peripherals on a single silicon die. Within the broader taxonomy, the PIC12CE519 belongs to the Microchip PIC10/12/16 mid-range family, which sits below 16-bit dsPIC and 32-bit PIC32 offerings but above 4-bit legacy controllers. The "OTP" designation indicates the program memory can be written only once, making this part suited for low-cost high-volume products where firmware is finalized at production.
Key features include 6 I/O pins with 25 mA source/sink capability per pin (sufficient to drive LEDs and small relays directly), four oscillator selections including an internal 4 MHz RC oscillator with programmable calibration, and a 200 ns instruction cycle for fast deterministic control loops. The part operates from 2.5 V to 5.5 V and supports a commercial temperature grade of 0 C to +70 C. The SOIJ-8 package (also referred to as 8-SOIJ) provides a low-profile SMT footprint approximately 5 mm long, suitable for space-constrained designs.
Architecturally, the PIC12CE519-04/SM uses a RISC Harvard architecture with separate program and data buses, 35 single-word instructions, and a hardware multiplier-free design optimized for low cost. The integrated 16-byte EEPROM is the primary differentiator versus the standard PIC12C508/509, allowing designers to store calibration constants, user settings, or serial numbers without an external memory chip. The four oscillator options include the calibrated internal 4 MHz RC, external RC, external crystal, and external clock modes.
Typical applications include low-cost consumer appliances, remote controls, LED lighting controllers, simple sensor interfaces, battery chargers, and white-goods subsystems where EEPROM-backed user settings and minimal PCB area matter. The 25 mA I/O drive eliminates the need for external transistors in many indicator or relay-driver circuits.
When designing with the PIC12CE519-04/SM, plan for in-system programming via ICSP (In-Circuit Serial Programming) since OTP cannot be reprogrammed; reserve an MCLR pull-up and dedicated ICSPCLK/ICSPDAT pins even if not used in production. The internal 4 MHz RC oscillator calibration register is factory-tuned but may drift over temperature; for timing-sensitive applications use an external crystal.

Ứng dụng tiêu biểu
PIC12CE519-04/SM phù hợp cho 6 Áp dụngs: Low-Cost Remote Control, LED Lighting Controller, Battery Charger Controller, White Goods User Interface, Simple Sensor Interface, Consumer Appliance Timer.
Low-Cost Remote Control
The PIC12CE519-04/SM is an ideal MCU for infrared remote controls, where its 4 MHz RISC core, 25 mA I/O drive, and 16-byte EEPROM combine to deliver a complete single-chip solution. The 200 ns instruction cycle is fast enough to generate 38 kHz carrier-frequency IR modulation, while the 6 I/O pins provide enough headroom for IR LED drive, button matrix scanning, and status LED feedback. The 16-byte EEPROM stores device pairing codes and customer configuration flags persistently, so the remote remains functional across battery swaps. Power consumption in sleep mode is sub-1 microampere, supporting year-long battery life from two AAA cells operating over the part's 2.5 V to 5.5 V supply range.

LED Lighting Controller
In LED lighting controllers the PIC12CE519-04/SM provides 25 mA per-pin I/O drive, sufficient to sink common-anode RGB or white LED strings directly without external MOSFETs in many configurations. The internal 4 MHz RC oscillator with programmable calibration provides deterministic PWM timing for dimming control, eliminating external crystal cost. The integrated 16-byte EEPROM stores last-set brightness and color-temperature preferences so user settings survive power cycles. The 1.5 KB OTP memory holds color-mixing algorithms and DMX-style address tables for architectural lighting. Commercial 0 C to +70 C operation covers indoor luminaires, while the PIC12CE519-04I/SM industrial variant extends coverage to outdoor fixtures.

Battery Charger Controller
For low-power battery chargers targeting NiMH cells or small Li-ion packs, the PIC12CE519-04/SM delivers the right balance of I/O, EEPROM, and ADC-free analog control. The 6 I/O pins handle charge-enable MOSFET gate drive, status LED, temperature sensor input via comparator, and push-button user interface. The 16-byte EEPROM stores charge cycle count, last-full-charge timestamp, and battery chemistry parameters for adaptive charging algorithms. Operating from 2.5 V to 5.5 V, the part is directly compatible with single-cell Li-ion and 2-3 cell NiMH packs. The 35-instruction RISC core is straightforward to program in assembly or C, and the 1.5 KB OTP fits typical CC/CV charge profiles with room for safety timers.

White Goods User Interface
In washing machines, dishwashers, and microwave ovens, the PIC12CE519-04/SM serves as a cost-optimized user-interface controller driving 7-segment displays, keypads, and buzzer feedback. The 25 mA per-pin drive directly multiplexes common-anode LED displays without driver transistors. The 16-byte EEPROM stores end-user preference settings (program selection, language, child-lock status) so settings survive power interruptions. With its 1.5 KB OTP holding the menu state machine and the 8-SOIJ package's small footprint, the device fits behind the front panel where PCB space is at a premium. Commercial 0 C to +70 C temperature range covers indoor appliance environments.

Simple Sensor Interface
For sensor-hub applications reading a single analog or digital sensor and transmitting the result via UART or PWM, the PIC12CE519-04/SM offers a minimal-footprint 8-pin solution. The 6 I/O pins handle sensor power switching, analog threshold detection, and serial output. The internal 4 MHz oscillator provides stable timing for software UART baud-rate generation at 9600 bps. The 16-byte EEPROM stores calibration coefficients and sensor identification, allowing field replacement without host reconfiguration. Operating from 2.5 V to 5.5 V the part interfaces directly with 3.3 V sensors and 5 V transceivers. Industrial-temperature-grade PIC12CE519-04I/SM is the preferred variant for outdoor sensor nodes.

Consumer Appliance Timer
In kitchen timers, fan controllers, and defrost-cycle modules, the PIC12CE519-04/SM provides the timing accuracy and I/O count needed in an 8-pin package. The internal calibrated 4 MHz RC oscillator supports time-base generation to within approximately +/-1 percent for short-duration timing, and the 16-byte EEPROM remembers last-used settings across power cycles. The 25 mA I/O drive directly switches small relays or TRIAC optocouplers for AC load control. With 6 I/O pins the MCU handles start/stop button input, status LED, buzzer, and one AC-load control output. The commercial temperature range of 0 C to +70 C suits indoor appliance use.

Ghi chú thiết kế
OTP memory can be programmed only once. Plan for ICSP (In-Circuit Serial Programming) access during development: dedicate the ICSPCLK (pin 12 equivalent on larger parts) and ICSPDAT pins and route them to a header, even if not used in production. Verify the MCLR pull-up resistor is correctly placed - if MCLR floats, the part may intermittently reset. Use a 10 kohm pull-up to VDD on MCLR pin (pin 3) per Microchip recommendation.
Add a 0.1 uF decoupling capacitor as close as possible to the VDD pin (pin 8), with a trace length under 5 mm to minimize inductance. For designs switching high-current loads via the I/O pins, add a bulk 10 uF tantalum or ceramic capacitor at the board power entry point. The internal 4 MHz RC oscillator draws additional supply current during start-up; if your design has a tight inrush budget, gate the MCU's VDD with a soft-start circuit.
The 8-SOIJ package has a center pad on the underside that is typically connected to VSS for thermal dissipation; solder this pad to a grounded copper pour to improve thermal performance and mechanical reliability. Keep high-speed traces (crystal, ICSP) short and away from switching noise sources. If using the external crystal oscillator mode, place the crystal within 5 mm of pins 1 and 2 with short symmetric traces and a grounded guard ring.
