MC9S08LH36CLK - 8-bit S08 MCU 40MHz 36KB Flash | NXP
MPN: MC9S08LH36CLK ✓ NakahandaMC9S08LH36CLK Ulas
An 8-bit microcontroller is an integrated circuit that combines a processor core, memory, and peripherals on a single chip, forming the lowest tier of the embedded-processor hierarchy (MCU -> embedded processor -> semiconductor). The S08 (HCS08) family from Freescale/NXP is a widely deployed 8-bit architecture used in cost-sensitive control tasks, sitting alongside families such as the HC08 legacy line and competing 8051 and PIC8 architectures.
Key features of the MC9S08LH36CLK include a 2.1 V to 3.6 V single-supply operating range, 36 KB of in-system-programmable FLASH with sector erase, and operation up to 40 MHz CPU clock (16 MHz bus operation is cited in some distributor parametric listings). The large 37-I/O count and 80-pin LQFP footprint make it suitable for designs needing many parallel control lines without port expanders.
Technically, the device is built around the HCS08 central processor unit with background debug mode (BDM) for non-intrusive in-circuit flashing and debugging. Distributor data describes lifecycle stage as ACTIVE, and the part is RoHS compliant per parametric listings. The LQFP-80 (14 x 14 mm) body provides 0.5 mm lead pitch for dense two-layer and four-layer PCB designs.
Typical applications include industrial control panels, consumer appliance control, LCD-segment-driven human-machine interfaces, and battery-powered instrumentation where 3V logic and low-cost 8-bit processing are sufficient.
Design consideration: verify whether your design requires the 40 MHz CPU-rated grade or only 20 MHz operation at 2.1 V, since available bus frequency scales with supply voltage per the S08 family datasheet.

Tipikal na mga Gamit
MC9S08LH36CLK ay nararapat para sa 6 aplikasyons: Industrial Control Panels, Appliance and Consumer Control, Human-Machine Interface (HMI) Boards, Battery-Powered Instrumentation, Legacy System Maintenance and Repair, Embedded Learning and Prototyping.
Industrial Control Panels
The MC9S08LH36CLK fits industrial control panels where dozens of discrete inputs and outputs must be scanned and driven without external port expansion. Its 37 I/O lines and 40 MHz S08 core handle relay sequencing, button debouncing, and indicator driving in a single 3.3 V-supplied 80-LQFP chip. The 36 KB FLASH accommodates state-machine firmware with headroom for communication routines. In-circuit BDM debugging lets technicians update firmware on installed boards through a single-wire header, minimizing downtime during control-logic revisions in factory environments.

Appliance and Consumer Control
Home appliances such as washing machines, cooktops, and environmental controllers historically used S08-family MCUs for their low cost and robust 8-bit architecture. The MC9S08LH36CLK operates from a 2.1 V to 3.6 V supply shared with common 3.3 V housekeeping rails, and its 80-LQFP body with 0.5 mm pitch suits cost-driven two-layer control boards. The 36 KB FLASH holds UI logic, safety interlock routines, and actuator timing. RoHS compliance keeps finished appliances compliant with European hazardous-substance restrictions without special sourcing.

Human-Machine Interface (HMI) Boards
HMI sub-boards benefit from the LH subfamily's segment-LCD driving heritage and the MC9S08LH36CLK's abundant I/O for keypads, LEDs, and buzzer control. The 40 MHz CPU updates display multiplexing and scans touch or mechanical keys with low latency, while 36 KB FLASH stores menus, glyphs, and event logging. Because the part is pin-compatible with the 64 KB MC9S08LH64CLK, a single HMI PCB layout can serve both cost-optimized (36 KB) and feature-optimized (64 KB) product tiers, simplifying procurement and layout reuse across product families.

Battery-Powered Instrumentation
Portable meters and dataloggers benefit from the wide 2.1 V to 3.6 V operating range of the MC9S08LH36CLK, which tolerates a discharging lithium cell directly at 3.0 V nominal without a regulator. The HCS08 core supports low-power wait and stop modes typical of the S08 architecture for extending battery life between duty-cycle wakes. The 36 KB FLASH retains calibration constants and logged data through the in-system programming mechanism. Designers should scale CPU frequency with battery voltage per the family datasheet, since 2.1 V operation is rated to 20 MHz rather than the full 40 MHz.

Legacy System Maintenance and Repair
Equipment fleets designed around the Freescale S08LH family require authorized continuation supply when original NXP stock is exhausted. The MC9S08LH36CLK, manufactured and distributed by Rochester Electronics, LLC, provides factory-new die for sustaining repairs of industrial drives, medical accessories, and communication modules. DigiKey and Mouser stock as of 2026-10-18 ships immediately, and RoHS-compliant LQFP-80 packaging directly replaces original fits. This makes the part a dependable choice for MRO organizations that must preserve form, fit, and function in legacy deployments without PCB redesign.
Inirekomenda
Embedded Learning and Prototyping
The S08 architecture remains a teaching platform for 8-bit embedded fundamentals, and the MC9S08LH36CLK's 80-pin LQFP exposes 37 I/O lines for breadboard-style prototyping on adapter boards. Single-wire BDM debugging requires only a low-cost P&E probe, letting students step code, watch registers, and flash firmware without JTAG complexity. The 36 KB FLASH is ample for coursework covering interrupts, timers, and serial communication. Free CodeWarrior-era toolchains and abundant S08 documentation lower the entry barrier for universities and hobbyists restoring classic 8-bit designs.

Talaan ng Disenyo
Power the MC9S08LH36CLK from a clean 3.3 V rail within its 2.1 V to 3.6 V range, and decouple each VDD/VSS pin pair with 100 nF ceramic capacitors placed within 2 mm of the pins, plus one bulk 10 uF capacitor near the package. Remember that bus frequency must scale with supply: at 2.1 V the family datasheet rates operation only up to 20 MHz, so firmware controlling clock configuration must enforce voltage-versus-frequency limits to avoid illegal operating points during brownouts.
The 80-LQFP (14 x 14 mm) has a 0.5 mm lead pitch; use solder-mask-defined pads per the manufacturer land-pattern recommendation and route a solid ground plane under the device. Bring the single-wire BDM debug pin to a 4-pin header (BKGD, RESET, VDD, GND) on every production PCB so in-circuit programming is possible after assembly. Keep crystal traces short and guarded by ground for the oscillator pins to maintain clock stability at 40 MHz operation.
Do not assume the distributor-listed 16 MHz figure contradicts the 40 MHz CPU rating: some parametric listings quote bus frequency while the family datasheet quotes CPU frequency. Confirm which clock your design timing budget uses. Also verify the exact temperature ordering code (C versus V suffix) against the full S08LH datasheet before release, since the retrieved data did not state the CL grade temperature range explicitly.
