Product details
Overview
MC9S08LG32CLH from NXP Semiconductors (formerly Freescale) is an 8-bit HCS08 microcontroller with 32 KB flash, 1984-byte RAM, and integrated LCD driver supporting up to 8×37 segments. It operates from 2.7 V to 5.5 V across –40 °C to 105 °C, features dual TPM modules (2+6 channels), 12-bit ADC with temperature sensor, and I²C/SPI/SCI interfaces. It targets automotive instrument clusters and industrial panel meters requiring low-power, high-integration timing and display control.
For engineers reviewing the MC9S08LG32CLH datasheet, MC9S08LG32CLH pinout, MC9S08LG32CLH application, or MC9S08LG32CLH equivalent, key selection considerations include its 80-pin LQFP package, stop3 mode wakeup time (100 µs), internal clock source (ICS) with ±2% deviation over voltage/temperature, and LCD charge pump enabling direct glass drive without external components.
Technical Context
The MC9S08LG32CLH implements the HCS08 CPU core with BGND instruction support and handles up to 32 interrupt/reset sources. Its clock system integrates a frequency-locked-loop (FLL) in the Internal Clock Source (ICS) module, trimmed for 0.2% resolution and ±2% deviation across full operating range.
Peripherals include a 12-bit ADC with 2.5 µs conversion time and wake-up capability from stop3 mode, dual TPM modules supporting input capture/output compare/PWM, and an on-chip LCD controller with internal charge pump - eliminating need for external bias circuitry in segment-based displays.

Pinout & Package
MC9S08LG32CLH is housed in an 80-pin LQFP (Case 917A, 14 mm × 14 mm) with exposed thermal pad. Pin functions are multiplexed across four priority levels per pin, with highest-priority function active by default after reset. Key dedicated pins include BKGD/MS (debug interface), RESET, XTAL/EXTAL (oscillator inputs), VCAP1/VCAP2 (voltage regulator bypass), and VLL1–VLL3 (LCD bias rails).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD / VSS | Power supply / Ground | Main digital power (2.7–5.5 V); VSS provides reference for all I/O and analog circuits |
| XTAL / EXTAL | Crystal oscillator inputs | Accepts 31.25 kHz–16 MHz crystal/resonator; enables precise clock source for RTC and LCD timing |
| BKGD/MS | Single-wire background debug | Enables in-circuit debugging, breakpoint setting, and flash programming via single pin |
| RESET | Active-low reset input | Asynchronous reset assertion clears CPU registers and initiates boot sequence from vector table |
| VCAP1 / VCAP2 | Voltage regulator bypass | Stabilizes internal 2.5 V regulator output; requires 1 µF ceramic capacitor to VSS per pin |
| VLL1 / VLL2 / VLL3 | LCD bias voltage outputs | Generated internally for LCD segment/backplane drive; eliminates need for external resistor ladder |
| PTE0–PTE7 | LCD segment drivers | Drive LCD segments LCD0–LCD15; configurable as GPIO when LCD disabled |
| PTA0–PTA7 | Multiplexed I/O / ADC / TPM / LCD | Support LCD21–LCD28, ADC0–ADC5, TPMCLK, and KBI4–KBI7 - enables compact display + sensing designs |
Key Features
| Feature | Design Value |
|---|---|
| On-chip LCD controller with charge pump | Drives up to 8×37 segments directly - removes external bias IC and reduces BOM count |
| Stop3 low-power mode | Typical 100 µs wakeup time with RTC and ADC fully functional - ideal for periodic sensor polling |
| Internal Clock Source (ICS) with FLL | ±2% accuracy over full temp/voltage range - eliminates need for external crystal in cost-sensitive applications |
| Security circuitry | Prevents unauthorized read-out of flash and RAM contents - protects firmware IP in production units |
| Single-wire background debug (BKGD) | Enables full ICE functionality (breakpoints, trace, memory access) using only one pin - simplifies PCB layout |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S9KEAZN64ACLH | ARM Cortex-M0+ core, 64 KB flash, 8 KB RAM, no integrated LCD driver | Requires external LCD bias circuitry; higher performance but larger code footprint and power consumption | Choose when migrating to ARM ecosystem or needing >40 MHz throughput; not drop-in for LCD-centric designs |
| MC9S08LC32CLH | Same HCS08 core, 32 KB flash, but 48-pin LQFP and reduced LCD support (4×41 max) | Limited to smaller displays; fewer GPIOs (39 vs. 69) and no VLL3_2 rail | Select for space-constrained panels where full 8×37 LCD drive is unnecessary and BOM cost is critical |
Compared with S9KEAZN64ACLH and MC9S08LC32CLH, the MC9S08LG32CLH uniquely delivers integrated LCD bias generation, 80-pin I/O scalability, and stop3-mode wakeup optimized for display-intensive embedded systems - making it irreplaceable in legacy HCS08-based instrument designs requiring minimal external components.

FAQ
What is the maximum operating frequency of the MC9S08LG32CLH?
The MC9S08LG32CLH supports a maximum CPU frequency of 40 MHz at 5.5 V supply voltage within its specified temperature range of –40 °C to 105 °C. This frequency is achievable using the Internal Clock Source (ICS) with FLL enabled and properly configured, or via external crystal oscillator input through XTAL/EXTAL pins.
Does the MC9S08LG32CLH support LCD bias generation without external components?
Yes, the MC9S08LG32CLH integrates an on-chip LCD controller with internal charge pump and three dedicated bias rails (VLL1, VLL2, VLL3). This enables direct driving of up to 8×37 segment LCDs without external resistors, capacitors, or bias ICs - significantly reducing bill-of-materials and board area.
What is the wakeup time from stop3 mode for the MC9S08LG32CLH?
The MC9S08LG32CLH has a typical wakeup time of 100 µs from stop3 mode. During this mode, the RTC remains active and the 12-bit ADC can be triggered to wake the CPU - enabling precise, low-energy periodic sensing tasks such as temperature monitoring or LCD refresh scheduling.
How many ADC channels does the MC9S08LG32CLH provide, and what is their resolution?
The MC9S08LG32CLH includes a 12-bit successive approximation ADC with up to 16 input channels. It features automatic compare, temperature sensor integration, internal bandgap reference, and full functionality down to 2.7 V supply - allowing accurate analog measurements even in low-voltage battery-operated systems.
Is the MC9S08LG32CLH pin-compatible with other members of the MC9S08LGxx series?
The MC9S08LG32CLH shares the same 80-pin LQFP package and pinout with MC9S08LG32 variants (e.g., MC9S08LG32CLH vs. MC9S08LG32CPJ), but is not pin-compatible with 48-pin or 64-pin LG-series parts like MC9S08LG16CLH due to differing pin counts and function mappings - always verify against the specific device's pin assignment table.
