MC908JL16CPE - 8-bit HC08 MCU, 16KB Flash, 28-DIP | NXP
MPN: MC908JL16CPE ✗ Cuối đờiMC908JL16CPE Tóm tắt
An 8-bit microcontroller is a single-chip computer that integrates a CPU, program memory (FLASH/ROM), data memory (RAM), timers, I/O and peripheral interfaces onto one silicon die, intended for embedded control rather than general-purpose computing. HC08-class MCUs sit at the low end of the M68HC08 hierarchy within NXP/Freescale's broader 8-bit microcontroller family (HC08 -> 8-bit MCU -> microcontroller -> embedded processor -> semiconductor). This taxonomy matters because choosing an HC08 part determines toolchain, instruction set, and peripheral selection for a given design.
Key features of the MC908JL16CPE include 16 KB of FLASH, an 8 MHz maximum internal bus frequency, an integrated ADC with up to 10-bit resolution per comparison sheets, on-chip oscillator and timer resources typical of the HC08JL sub-family, multiple I/O lines, and a multi-source interrupt controller. The device runs across the standard industrial temperature range and supports low-power stop and wait modes for battery-sensitive designs. The 28-pin DIP package simplifies prototyping with breadboards and through-hole pads.
Architecturally, the MC908JL16CPE is implemented in a fully-static CMOS process and uses a von-Neumann-style memory map (common to HC08 MCUs) with a 16-bit stack pointer, hardware multiply, and BCD instructions. The integrated FLASH lets developers erase/reprogram in-circuit, which lowers NRE cost for small-to-medium production runs. The peripheral set is intentionally compact - the JL-series is positioned as a cost-trimmed variant - allowing the part to compete on price/performance in volume consumer and appliance sockets.
Typical applications include white-goods and appliance control (washing machines, microwave ovens, induction cookers), simple motor control for small DC and BLDC fans/pumps, IR remote-control receivers, low-end key-scanning keypads, battery chargers, LED lighting controllers, and consumer remote sensor/transmitter modules. The DIP-28 form factor is also attractive in university curricula and hobbyist designs.
For design, ensure your toolchain supports HC08 object code (CodeWarrior HC08, ICC08, or compatible). Add a 0.1 uF decoupling capacitor close to each VDD pin, and respect the oscillator startup time defined in the datasheet's electrical characteristics before relying on the clock. Verify in-system programming voltage and timing against the FLASH row-erase / page-program specs in the datasheet.

Ứng dụng tiêu biểu
MC908JL16CPE phù hợp cho 7 Áp dụngs: White Goods Appliance Control, Small Motor and Fan Control, IR Remote Control Receivers, Battery Chargers, LED Lighting Controllers, Industrial Keypads and HMI, Educational and Prototyping Platforms.
White Goods Appliance Control
The MC908JL16CPE suits washing machine, microwave oven, and induction cooker control panels where cost and 8-bit determinism dominate the design decision. Its 16 KB FLASH supports typical user-interface state machines, keypad handling, timer scheduling, and relay/SSR drive logic without needing external memory. Operating from -40C to +85C industrial range, it handles under-cabinet and motor-bay thermal envelopes. The 8 MHz internal bus and integrated ADC let the MCU read temperature sensors (NTC), mains zero-cross detectors, and triac feedback - all functions common in white-goods control loops.
Được đề xuất
Small Motor and Fan Control
With its 10-bit ADC and HC08 timers, the MC908JL16CPE fits low-end BLDC, brushed DC, and induction motor control for fans, pumps, and small appliances. The timer module generates PWM for MOSFET gate drive, while the ADC samples back-EMF or shunt current for closed-loop speed/torque control. The 28-DIP package eases field servicing through the product lifecycle. The fully-static CMOS core means PWM frequency is stable across package tolerances, and the low-power wait mode supports standby current budgets typical of consumer motor drives.
Được đề xuất
IR Remote Control Receivers
The MC908JL16CPE fits IR remote receiver designs for HVAC, lighting, and consumer AV equipment, where 16 KB FLASH supports manufacturer-specific protocol stacks (RC5, NEC, custom). The HC08 interrupt structure plus low-power wait mode keeps standby current in the microamp range between button events, extending battery life. The ADC can read battery voltage for low-battery indication, while general-purpose I/O lines drive status LEDs directly with no external drivers needed. Through-hole DIP-28 simplifies hand-soldered prototype testing for remote enclosure designs.
Được đề xuất
Battery Chargers
The MC908JL16CPE is well suited to single- and multi-cell NiMH, Li-ion, and lead-acid chargers in the 1-10A range, where the 10-bit ADC monitors charging current, battery voltage, and temperature, while HC08 timers control PWM switching. Sixteen kilobytes of FLASH holds multi-stage charge profiles (bulk, absorption, float, equalization) plus safety timers and LED UI logic. Stop and wait low-power modes reduce quiescent draw when the charger is plugged in but no battery is connected, satisfying energy-efficiency regulations.
Được đề xuất
LED Lighting Controllers
In LED drivers and color-mixing fixtures, the MC908JL16CPE combines 16 KB FLASH for lookup-table-driven dimming curves and color-temperature presets with 10-bit PWM channels for smooth dimming. The HC08 timers generate the high-frequency PWM needed to avoid visible flicker, while the ADC reads ambient light sensors for daylight harvesting. Stop and wait modes enable standby watt budgets below 0.5 W, compliant with EU and US efficiency regulations for lighting.
Được đề xuất
Industrial Keypads and HMI
The MC908JL16CPE's multiple I/O lines and interrupt structure make it a strong fit for 4x4 to 8x8 matrix keypads and small HMIs used in industrial control panels and access-control terminals. Sixteen kilobytes of FLASH supports debounce algorithms, multi-language lookup tables, and access-control lists. The DIP-28 package suits hand-assembled prototype panels and field-replaceable module designs. Integrated ADC channels can read panel-mounted potentiometers for setpoint adjustment, while timers drive piezo buzzers for feedback.
Được đề xuất
Educational and Prototyping Platforms
The MC908JL16CPE's 28-DIP through-hole package is breadboard-friendly and well matched to university curricula teaching 8-bit embedded programming, assembly, and interrupt-driven design. The HC08 instruction set is simple enough for first-time learners, while the 16 KB FLASH and on-chip peripherals provide enough room to implement realistic labs (UART communication, ADC sampling, timer-based scheduling). CodeWarrior HC08 and SDCC toolchains are free or low-cost, and P&E BDM pods support in-circuit debug and programming at a price students can afford.

Ghi chú thiết kế
Place a 0.1 uF decoupling capacitor within 5 mm of every VDD pin (pin 3 and any additional VDD pins per datasheet) and a 10 uF bulk capacitor near the regulator. HC08 MCUs have low current draw, but the VDD rise time must remain within the datasheet's specified range during power-up to avoid spurious reset behaviour. Use a supervisor or simple RC reset if the regulator has slow ramp.
Keep the OSC1/OSC2 traces short and symmetric. For a crystal oscillator, place the crystal and load capacitors within 5 mm of OSC1/OSC2 with a ground guard ring to minimize EMI pickup. Long, parallel routing of OSC traces to I/O lines couples switching noise into the clock and causes timing drift in timer/PWM applications.
Estimated: FLASH in-system programming requires VDD to be within the datasheet's specified tolerance with adequate decoupling - drops below the minimum VDD during programming can corrupt FLASH. When using BDM (Background Debug Mode), the BKGD pin must be pulled according to the datasheet during reset to enter debug mode; floating the BKGD pin in production can cause accidental debug entry. The IRQ pin has an internal pull-up; if left unused, leave it open or driven high to avoid spurious interrupts.
The 28-DIP package has moderate thermal resistance (estimated 70-90 C/W theta_JA in still air). At typical HC08 current draws (< 30 mA active), self-heating is negligible and no heatsink is needed. In enclosed fixtures above 60C ambient, verify junction temperature remains below 125C with a thermal spot check during characterization.
For PWM-driven outputs to FETs or LEDs, add a 100 ohm series resistor at the MCU pin if the trace exceeds 50 mm or crosses a high-dV/dt signal, to dampen ringing. HC08 outputs are relatively slow (rise times ~10-20 ns), but in noisy motor-drive environments ringing can couple into the analog ADC channels and bias readings; place ADC input traces away from PWM outputs.
