Product details
Overview
MC9S08LC36LH from NXP Semiconductors (formerly Freescale) is an 8-bit HCS08 microcontroller with 36 KB on-chip FLASH, 2.5 KB RAM, and integrated LCD driver supporting up to 4×32 segments in 64-pin LQFP package. It features a 40-MHz CPU core, 12-bit ADC with temperature sensor, dual SPI, I²C, SCI, two TPM modules, and hardware real-time interrupt (RTI) for embedded timing control. Used in low-power industrial displays and appliance control panels.
For engineers reviewing the MC9S08LC36LH datasheet, MC9S08LC36LH pinout, MC9S08LC36LH application, or MC9S08LC36LH equivalent, key selection criteria include FLASH size (36 KB), LCD segment drive capability (4×32), operating voltage range (2.7–5.5 V), stop-mode current (<1 µA), and 64-pin LQFP mechanical compatibility.
Technical Context
The MC9S08LC36LH implements the HCS08 CPU core with HC08 instruction set extension including BGND for background debugging. It supports multiple low-power modes (Wait, Stop1/Stop2/Stop3) with selective peripheral clock gating and software-controlled slew rate/drive strength per port pin.
Its LCD driver operates directly from internal charge pump (VLCD), supports both 3-V and 5-V glass, and remains functional in Wait and Stop3 modes. The 12-bit ADC includes asynchronous clocking, hardware trigger via RTI, and internal bandgap reference - enabling precise sensor monitoring without CPU intervention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | HCS08 8-bit CPU, 40 MHz max frequency - enables deterministic real-time control at sub-25 ns instruction cycle. |

Pinout & Package
MC9S08LC36LH is housed in a 64-pin LQFP (10 mm × 10 mm, 0.5 mm pitch) with exposed thermal pad. Pin functions are defined across Ports A, B, C, and dedicated peripheral pins (XTAL, EXTAL, BKGD/MS, RESET, VLCD, VREFH/VREFL).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PTA0–PTA7 | Port A general-purpose I/O | 8-bit bidirectional port with individual pullup/slew/drive control; PTA7 is output-only - usable for fixed-function outputs like LCD backplane. |
| PTB0–PTB7 | Port B general-purpose I/O | 8-bit bidirectional port; PTB0–PTB1 support KBI edge detection; PTB2–PTB3 support SCI/SPI functions. |
| PTC0–PTC7 | Port C general-purpose I/O | 8-bit port; PTC7 is input-only; PTC0–PTC3 support TPM1/TPM2 channels; PTC4–PTC6 support SPI2/IIC. |
| VLCD | LCD charge pump output | Internally generated LCD bias voltage - eliminates need for external DC-DC converter in segment LCD designs. |
| BKGD/MS | Background debug / mode select | Single-wire debug interface pin - enables in-circuit programming and real-time debugging without JTAG header. |
| RESET | Active-low reset input | Internal pullup ensures reliable startup; accepts external reset assertion or watchdog timeout signal. |
Key Features
| Feature | Design Value |
|---|---|
| Configurable Clock Source | Crystal, resonator, external clock, or internal trimmed RC oscillator - enables flexible BOM optimization and layout simplification. |
| Software-Controlled Port Drive | Per-pin slew rate and drive strength selection - reduces EMI and optimizes signal integrity for mixed-signal PCB routing. |
| Hardware-Triggered ADC | RTI counter initiates conversion autonomously - frees CPU for other tasks while maintaining precise sampling intervals. |
| Low-Voltage Detection | Programmable LVD threshold with reset or interrupt option - prevents erratic operation during brown-out conditions. |
| On-Chip Security | FLASH block protection and security byte lock - protects firmware IP against unauthorized readout or reprogramming. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC9S08LC60LH | 60 KB FLASH, 4 KB RAM, same 64-pin LQFP package and peripheral set - larger memory footprint with identical pinout and clock architecture. | Required when firmware exceeds 36 KB or additional RAM buffers are needed for protocol stacks. | Select MC9S08LC60LH if future firmware expansion or complex communication protocols demand more memory headroom. |
| S9KEAZN32ACLH | Kinetis E-series ARM Cortex-M0+ core, 32 KB FLASH, 4 KB RAM, 64-pin LQFP - higher performance, newer architecture, but no integrated LCD driver. | Suitable for next-generation designs where LCD is replaced by graphical display or external controller. | Choose S9KEAZN32ACLH only when migrating from 8-bit to 32-bit and LCD functionality is handled externally. |
Compared with MC9S08LC36LH, MC9S08LC60LH offers direct memory scalability within identical hardware constraints, while S9KEAZN32ACLH trades LCD integration for ARM ecosystem advantages - making MC9S08LC36LH optimal for cost-sensitive, LCD-centric legacy-compatible designs.

FAQ
What is the maximum operating frequency of the MC9S08LC36LH?
The MC9S08LC36LH supports a maximum core frequency of 40 MHz, achieved using its internal trimmed RC oscillator, crystal, or external clock source. This frequency enables sub-25 ns instruction execution cycles, making the MC9S08LC36LH suitable for time-critical control loops in industrial and appliance applications without requiring external PLL circuitry.
Does the MC9S08LC36LH include an integrated LCD driver?
Yes, the MC9S08LC36LH integrates a fully functional LCD driver supporting up to 4×32 or 3×33 segments in its 64-pin LQFP configuration. It generates VLCD internally via charge pump, eliminating external bias components, and remains operational in Wait and Stop3 low-power modes - a key differentiator for battery-powered display applications.
What power-saving modes does the MC9S08LC36LH support?
The MC9S08LC36LH supports Wait mode and three Stop modes (Stop1, Stop2, Stop3). Stop3 achieves <1 µA typical current at 3 V and -40°C to 85°C, with LCD driver and RTI active. This enables ultra-low-power operation ideal for devices requiring persistent display and periodic wake-up without external real-time clock ICs.
Can the MC9S08LC36LH perform ADC conversions without CPU involvement?
Yes, the MC9S08LC36LH ADC can be triggered autonomously by the Real-Time Interrupt (RTI) counter, allowing periodic sampling without CPU polling or interrupt overhead. Combined with its 12-bit resolution and internal bandgap reference, this makes the MC9S08LC36LH well-suited for continuous sensor monitoring in industrial and medical applications.
Is the MC9S08LC36LH pin-compatible with other members of the LC-series?
The MC9S08LC36LH shares identical 64-pin LQFP pinout and peripheral mapping with the MC9S08LC60LH, enabling drop-in replacement where FLASH/RAM requirements allow. However, it is not pin-compatible with 80-pin variants or non-LC-series HCS08 devices due to differing pin counts and peripheral assignments.
