MC9S08LC36LH - 8-bit S08LC MCU, 36KB Flash, 40MHz, LCD | NXP
MPN: MC9S08LC36LH ⚠ Lần mua cuốiMC9S08LC36LH Tóm tắt
An HCS08 microcontroller is a member of the 8-bit MCU category that uses the HC08 instruction set with extensions for low-power operation and on-chip peripherals; within the power management taxonomy, an 8-bit MCU belongs to the broader microcontroller > embedded controller > semiconductor device hierarchy. The MC9S08LC36LH combines CPU, memory (Flash + RAM), analog (ADC), communications (SCI/SPI/I2C), and LCD driving in a single chip, reducing external component count for cost-sensitive LCD human-machine-interface designs.
Key features confirmed from the verified datasheet extract include 40 MHz maximum CPU clock, 36 KB program Flash, an integrated LCD controller (the defining differentiator of the S08LC sub-family), 18 general-purpose I/O ports, and a 1.8V to 3.6V supply-voltage operating range. The device is specified for the LFQP / LQFP-64 (10 mm x 10 mm, 0.5 mm pitch, 1.40 mm height) package and is described as the first LCD S08 8-bit MCU in NXP's (formerly Freescale) portfolio aimed at battery-powered and handheld segments.
Architecturally, the S08LC integrates an HC08-compatible core augmented with a Background Debug mode (BGND) instruction, a Background Debug System (BDS) for in-circuit debugging, and breakpoint capability to allow single breakpoint setting during in-circuit debugging. On-chip peripherals typically found in the family include timers (TPM), real-time interrupt, ADC, and multi-master I2C plus SPI and SCI for asynchronous/synchronous serial.
Typical applications include battery-powered handheld instruments (medical meters, remote controls, utility readers), segment-LCD display modules (appliance controls, thermostats, point-of-sale terminals), and consumer / industrial HMI where a single-chip LCD + MCU solution reduces BOM. Its 1.8V minimum supply supports single-cell Li-primary or 2x AA Alkaline chemistries.
When designing with this MCU, careful decoupling (100 nF + bulk) is required near each VDD/VSS pair, and the LCD segment/Common pins require proper bias-resistor networks (typically a resistor ladder or charge-pump-based bias generation) to achieve specified contrast and low-quiescent LCD waveforms.

Ứng dụng tiêu biểu
MC9S08LC36LH phù hợp cho 6 Áp dụngs: Battery-Powered Handheld Instruments, Segment-LCD Display Modules (Appliance / Thermostat), Consumer HMI / Home Appliance Controls, Industrial Process Meters and Field Indicators, Medical Point-of-Care Devices, Automotive Auxiliary Displays.
Battery-Powered Handheld Instruments
Single-chip solution for battery-powered meters and remotes where low quiescent current and integrated LCD are required. The MC9S08LC36LH fits battery-powered handheld instruments because the integrated LCD controller removes the need for an external charge-pump LCD driver (a major quiescent contributor), and the 1.8 V to 3.6 V supply range lets it run directly from a single Li-primary cell or 2x AA Alkaline without a boost regulator. At 3.3 V with a 40 MHz CPU, the firmware can scan user input, run a measurement loop, and refresh the segment display while drawing typically low-uA average current in STOP/WAIT low-power modes between user events, extending battery life versus a discrete MCU + LCD-driver design. Use case: digital kitchen thermometers, IR remote controls, single-cell utility AMR modules.

Segment-LCD Display Modules (Appliance / Thermostat)
Direct driving of TN segment LCDs in appliances without external LCD bias generation IC. The MC9S08LC36LH's on-chip segment-LCD controller can drive typical 4-common x 32-segment displays in 1/3 bias, 1/4 duty using an external resistor ladder or charge-pump bias network - keeping the BOM minimal for appliance user-interface boards. The 40 MHz core handles key-scan debouncing, RTC tick, and user-interface state machines without timing pressure; the integrated LCD waveform generator avoids the firmware overhead and inconsistent contrast of a software-driven mux scheme. Use case: washing-machine control panels, microwave ovens, room thermostats, point-of-sale terminals.
Được đề xuất
Consumer HMI / Home Appliance Controls
Low-cost user interface board with LCD and push-button or capacitive touch input. The 18 GPIOs on the MC9S08LC36LH are sufficient to scan a typical 4x4 key matrix while still leaving LCD segment pins free, in part because the chip's segment-I/O pin mux is designed for combined LCD-plus-key-scan use. Programming is via the standard Freescale/NXP Background Debug Mode, so no expensive JTAG hardware is needed - a $30 P&E BDM pod suffices for in-circuit programming of the 36 KB Flash in production. Use case: HVAC indoor units, white-good control boards, espresso machines, induction cooktops.

Industrial Process Meters and Field Indicators
Loop-powered or battery-backed industrial field meters with on-glass segment LCD readout. The 1.8 V minimum supply lets the MC9S08LC36LH operate from a 4-20 mA current loop with a series resistor / shunt regulator, and the LCD output is readable in the dimmest industrial lighting without a backlight, reducing power draw. The HC08 core plus SCI (UART) supports Modbus RTU or proprietary sensor-bus protocols at common baud rates; the integrated ADC and timers handle transducer sampling and pulse-counting from flow or rotation meters. Use case: process level gauges, flow totalizers, pressure transmitters with local LCD readout.

Medical Point-of-Care Devices
Compact, battery-powered diagnostic devices with on-board segment-LCD user feedback. The MC9S08LC36LH's low-voltage operation and integrated LCD make it well-suited to portable medical devices such as blood-glucose meters, pulse oximeters, and INR readers, where size, battery life, and clear numeric display drive the BOM. Its 8-bit HC08 core and 36 KB Flash can run the simple state machines typical of POC devices with firmware room for calibration tables and diagnostic sequences; the Background Debug System allows service-mode firmware updates in the field. Use case: glucose meter, INR meter, handheld pulse oximeter, single-parameter vital-sign monitors.
Được đề xuất
Automotive Auxiliary Displays
Segment-LCD cluster readouts and accessory control displays in automotive interior applications. Although the MC9S08LC36LH itself is not AEC-Q100 qualified, its wide supply range and integrated LCD have made it a candidate in non-safety automotive sub-systems such as cabin climate controls, after-market accessory displays, and tire-pressure-monitoring (TPMS) hand-held readers. For TPMS service tools and OBD-II accessory modules, designers pair the MC9S08LC36LH with an external CAN or K-Line transceiver and use the segment LCD to display pressure, temperature, and battery telemetry from the tire sensors. Use case: after-market TPMS service tools, cabin HVAC accessory boards, OBD-II code-reader LCDs.

Ghi chú thiết kế
Place a 100 nF ceramic decoupling capacitor as close as possible to every VDD/VSS pin pair of the MC9S08LC36LH, and add a single 4.7 uF to 10 uF bulk capacitor near the supply rail entry. The integrated LCD controller's quiescent current is sensitive to VDD ripple above 50 mV peak-to-peak - insufficient decoupling produces visible LCD contrast variation and inaccurate analog readings on ADC channels that share the VDD pin. For battery-powered designs, route the LCD bias resistor ladder to a switched node (PTCx high-impedance when LCD is off) to drop bias current to zero in STOP mode.
Do not assume the LCD segment pins are usable as general-purpose GPIO when the LCD controller is active - the LCD waveform generator drives those pins automatically and overrides the GPIO data direction. To avoid spurious current spikes, configure unused LCD pins to analog (high-impedance) mode rather than leaving them as digital inputs (which float and draw bias current through the LCD resistor ladder). For unused GPIO, set the data direction to output and drive to a defined logic level.
Keep the BKGD and RESET traces short (less than 50 mm if possible) and route them away from the LCD segment Common outputs and from any switching power-supply traces. The BDM input is sensitive to noise spikes; reset glitches below 100 ns can trigger spurious resets and corrupt Flash programming. Place a 10 kohm pull-up on RESET to VDD and a series resistor (1 kohm to 4.7 kohm) on BKGD for debug-port protection in production boards.
