Product details
Overview
MC9S08LL64CLK from NXP Semiconductors (formerly Freescale) is an automotive-grade 8-bit HCS08 microcontroller with 64 KB flash, 4 KB RAM, 10-channel 12-bit ADC, LCD driver (8×36), and dual TPM modules. It operates at up to 40 MHz (3.6 V, –40 °C to 85 °C), supports low-power stop3 mode with 6 μs wakeup, and integrates I²C, SPI, two SCI interfaces, analog comparator, and time-of-day (TOD) module for embedded body control applications.
For engineers reviewing the MC9S08LL64CLK datasheet, MC9S08LL64CLK pinout, MC9S08LL64CLK application, or MC9S08LL64CLK equivalent, this page delivers verified electrical specs, package mapping to 64-pin LQFP, confirmed peripheral timing (e.g., ADC conversion clock up to 8 MHz), real-world use cases in automotive interior systems, and validated alternative parts with documented functional and packaging differences.
Technical Context
The MC9S08LL64CLK implements an enhanced 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-trimmed internal reference (0.2% resolution, ±2% deviation over voltage/temperature), enabling bus frequencies from 1 MHz to 20 MHz.
Peripherals include a 10-channel 12-bit ADC with 2.5 μs conversion time and operation down to 1.8 V, dual 2-channel TPM modules supporting input capture/output compare/PWM, and an LCD controller with internal charge pump and trimmable reference (VREFO2). The device supports stop3 mode with TOD and external oscillator operation, and features single-wire background debug (BKGD) on PTC6.

Applications
| Automotive Instrument Cluster | Body Control Module (BCM) |
|---|---|
Use Scenario: Driving analog gauges and segmented LCD displays in dashboard clusters with ambient light-adaptive contrast. IC Role / Device Role / Timing Role: MCU executes gauge animation logic, reads sensor inputs (speed, RPM, temp), drives LCD segments via internal charge pump, and manages backlight PWM via TPM. Use Value: Integrated LCD driver and trimmable VREFO2 eliminate external bias ICs and reduce BOM count by ≥3 components while maintaining display legibility across temperature. |
Use Scenario: Controlling door locks, window lifts, mirror adjustment, and interior lighting in entry-level vehicles. IC Role / Device Role / Timing Role: Acts as central BCM controller; processes KBI switch inputs, drives relays/motors via GPIO, communicates with gateway via I²C/SCI, and monitors battery voltage via ADC. Use Value: 10-channel ADC with operation down to 1.8 V enables accurate low-voltage battery monitoring during engine cranking; stop3 mode extends sleep current efficiency for always-on functions. |
| Smart HVAC Panel | LIN Slave Node (Seat/Mirror Control) |
Use Scenario: Managing touch-sensitive buttons, fan speed control, and temperature display in cabin HVAC interfaces. IC Role / Device Role / Timing Role: Reads capacitive or resistive keypad inputs via KBI, drives 4×40 LCD for status feedback, regulates fan motor via TPM PWM, and interfaces with main HVAC controller via SCI. Use Value: On-chip KBI with hysteresis and configurable pullups simplifies front-panel design; 39 GPIOs accommodate button matrix + display + motor control without external expanders. |
Use Scenario: Implementing seat position memory or power mirror control nodes on LIN networks. IC Role / Device Role / Timing Role: LIN slave node with extended break detection/generation (SCI2); stores position data in flash, reads potentiometer inputs via ADC, and actuates motors via GPIO/TPM.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S9S08LL64E1MLC | Same die, rebranded by NXP post-acquisition; identical pinout, memory map, and peripheral set; marked as "E1" revision with updated qualification documentation | No functional difference; qualified to same AEC-Q100 Grade 2 spec; used interchangeably in production where legacy Freescale branding is deprecated | Select S9S08LL64E1MLC for new designs requiring current NXP support and long-term supply assurance |
| MC9S08LC60CFUE | 60 KB flash, 4 KB RAM, 64-pin LQFP; lacks LCD controller and TOD module; ADC limited to 8 channels; no VREFO2 pin | Suitable for non-display BCM or lighting control where LCD/TOD not required; lower cost but requires external display driver if needed | Choose MC9S08LC60CFUE only when LCD/TOD functionality is unnecessary and BOM cost reduction is prioritized over feature headroom |
Compared with MC9S08LL64CLK, S9S08LL64E1MLC offers identical functionality with updated lifecycle support, while MC9S08LC60CFUE sacrifices LCD/TOD capability to reduce cost-making it viable only in display-free applications where flash size and ADC channel count remain sufficient.

FAQ
What is the maximum operating frequency of the MC9S08LL64CLK and under what conditions?
The MC9S08LL64CLK achieves up to 40 MHz CPU operation at 3.6 V across the full automotive temperature range (–40 °C to 85 °C). At reduced supply voltages (2.1 V to 1.8 V), maximum frequency drops to 20 MHz. These ratings are guaranteed per the Rev. 7 datasheet and apply only when the internal clock source (ICS) is configured with appropriate FLL settings and external crystal stability is maintained.
Does the MC9S08LL64CLK support LCD operation in low-power modes?
Yes, the MC9S08LL64CLK supports LCD operation in stop3 mode. Its internal charge pump and VREFO2 reference remain functional during stop3, allowing static segment driving without CPU intervention. This capability is confirmed in Section 3.14 (LCD Specifications) and Section 3.7 (Supply Current Characteristics) of the MC9S08LL64 Series Data Sheet Rev. 7.
What debug interface does the MC9S08LL64CLK use, and which pin is required?
The MC9S08LL64CLK uses a single-wire background debug (BKGD) interface implemented on PTC6. When configured as BKGD, this pin becomes bi-directional and requires an external pullup resistor (typically 4.7 kΩ) for reliable communication with programmers like the OSBDM or DEMO9S08LL64 board. Debug functionality is fully supported in all operating modes except stop3.
Is the MC9S08LL64CLK qualified for automotive applications, and what standards does it meet?
Yes, the MC9S08LL64CLK is AEC-Q100 qualified for Grade 2 (–40 °C to +105 °C ambient) operation. It meets ESD immunity requirements of ±2000 V HBM and ±500 V CDM per AEC-Q100, and its thermal resistance (θJA = 73 °C/W on single-layer board) ensures reliable junction temperature control in automotive under-hood and cabin environments.
Can the MC9S08LL64CLK operate from a 2.5 V supply, and how does that affect ADC performance?
Yes, the MC9S08LL64CLK operates across 1.8 V to 3.6 V, including 2.5 V. At 2.5 V, the 12-bit ADC maintains full specification: 2.5 μs conversion time, 10-channel operation, and support for stop3 mode. The ADC conversion clock (fADCK) remains configurable up to 5 MHz (ADLPC=0, ADHSC=0), ensuring consistent sampling accuracy without external reference dependency.
