Product details
Overview
MC9S08LL36CLK from NXP Semiconductors (formerly Freescale) is an 8-bit HCS08 core microcontroller designed for low-power automotive and industrial LCD display applications. It features 36 KB flash (24,576 + 12,288 arrays), 4 KB RAM, 8-channel 12-bit ADC with 2.5 μs conversion time, and integrated LCD driver supporting up to 8×24 or 4×28 segments. It operates from 1.8 V to 3.6 V across –40 °C to +85 °C.
For engineers reviewing the MC9S08LL36CLK datasheet, MC9S08LL36CLK pinout, MC9S08LL36CLK application, or MC9S08LL36CLK equivalent, this page delivers verified technical context, package-specific pin mapping, real-world use cases in automotive instrument clusters and industrial HMIs, and validated alternative options for supply continuity and design flexibility.
Technical Context
The MC9S08LL36CLK implements the HCS08 CPU core with BGND instruction support and handles up to 32 interrupt/reset sources. Its internal clock source (ICS) uses a frequency-locked loop (FLL) with precision trimming for ±0.2% resolution and ±2% deviation over voltage/temperature, enabling bus frequencies from 1 MHz to 20 MHz.
It integrates dedicated low-power peripherals including a time-of-day (TOD) module with external clock input, dual TPM modules (2-channel each), two full-duplex SCI interfaces with LIN break support, and an analog comparator with stop3-mode operation. The device supports two low-power stop modes and achieves 6 μs typical wakeup from stop3.

FAQ
What is the maximum operating frequency of the MC9S08LL36CLK?
The MC9S08LL36CLK supports up to 20 MHz bus frequency at 2.1 V–3.6 V and up to 40 MHz at 3.6 V within the –40 °C to +85 °C range. Its ICS module uses a frequency-locked loop (FLL) with internal reference trimming to maintain stability across voltage and temperature variations. The actual achievable frequency depends on supply voltage and configuration of the FLL multiplier and divider registers.
Does the MC9S08LL36CLK support LCD bias generation without external components?
Yes, the MC9S08LL36CLK includes an integrated charge pump and programmable LCD voltage regulator that generates VLCD from VDD. It supports 8×24 or 4×28 segment drive configurations and allows contrast adjustment via software-controlled VREFO2 trimming. No external capacitors or resistors are required for basic LCD biasing, though external caps may be added for noise reduction in high-noise environments.
Can the MC9S08LL36CLK operate in stop3 mode while maintaining RTC functionality?
Yes, the MC9S08LL36CLK supports time-of-day (TOD) operation in stop3 mode using its very low-power external oscillator (XOSC) running from a 32.768 kHz crystal. The TOD module retains counting and match register functionality during stop3, enabling accurate calendar/timekeeping with sub-μA quiescent current - ideal for battery-backed clocks in thermostats or instrumentation.
What debug interface does the MC9S08LL36CLK provide?
The MC9S08LL36CLK features a single-wire background debug (BKGD) interface on PTC6, compatible with standard BDM tools like the PE Micro Cyclone PRO. It supports full in-circuit emulation, including three hardware breakpoints, memory inspection, register view, and real-time trace via the on-chip ICE module - all without requiring additional debug pins or JTAG headers.
Is the MC9S08LL36CLK pin-compatible with other devices in the LL-series?
The MC9S08LL36CLK shares the same 64-pin LQFP (case 840F) package and pinout with MC9S08LL36 variants (e.g., MC9S08LL36CLH), but is not pin-compatible with MC9S08LL64CLK, which uses an 80-pin LQFP. Key differences include VREFO2 presence (pin 26) on MC9S08LL36CLK versus VREFO1 on MC9S08LL64CLK, and reduced LCD segment count (24 vs. 36).
