Product details
Overview
MC9S08DN32AMLF from NXP Semiconductors (formerly Freescale) is an 8-bit HCS08 microcontroller with 32 KB flash, 2 KB RAM, and 2 KB EEPROM, featuring a 40-MHz CPU core (20-MHz bus), integrated 12-bit ADC, dual analog comparators, SCI with LIN 2.0 support, SPI, I²C, two TPM modules, RTC, and real-time interrupt capability. It targets automotive body electronics and industrial control systems requiring robust on-chip memory and mixed-signal peripherals.
For engineers reviewing the MC9S08DN32AMLF datasheet, MC9S08DN32AMLF pinout, MC9S08DN32AMLF application, or MC9S08DN32AMLF equivalent, key selection criteria include flash/EEPROM size, 12-bit ADC channel count and conversion time, LIN-capable SCI interface, low-power stop modes, and LQFP-48 package compatibility for space-constrained automotive modules.
Technical Context
The MC9S08DN32AMLF implements the HCS08 CPU core with HC08 instruction set extension (including BGND), supporting up to 32 interrupt/reset sources and single-wire background debug. Its Multi-Purpose Clock Generator (MCG) provides FLL and PLL modes with factory-trimmed internal reference clock and ±1.5% FLL accuracy using temperature compensation.
On-chip peripherals include a 16-channel 12-bit ADC with 2.5 μs conversion time and internal temperature sensor, two analog comparators with bandgap reference option, one LIN 2.0–compliant SCI, full-duplex SPI with double buffering, I²C at up to 100 kbps, and two Timer Pulse-Width Modulators (TPM1: 6-channel; TPM2: 2-channel) supporting input capture, output compare, and PWM generation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | HCS08 8-bit core, 40-MHz operation (20-MHz bus speed); enables deterministic real-time control in cost-sensitive embedded applications. |
| Flash Memory | 32 KB on-chip flash with read/program/erase over full voltage/temperature range; supports in-circuit reprogramming and flash block protection. |
| RAM / EEPROM | 2 KB RAM for runtime variables; 2 KB EEPROM with 4-/8-byte erase sectors and program/erase while executing flash - critical for data logging and calibration storage. |
| ADC | 16-channel, 12-bit resolution, 2.5 μs conversion time, internal temperature sensor, and automatic compare function - suitable for precision sensor interfacing without external signal conditioning. |
| Communication | SCI with LIN 2.0/SAE J2602 compliance, SPI (master/slave, double-buffered), and I²C (100 kbps, multi-master) - enables interoperability in automotive sub-networks and sensor hubs. |
| Power Modes | Two very low-power stop modes (Stop2/Stop3), reduced-power wait mode, and 1-kHz real-time interrupt - extends battery life in always-on vehicle modules like door controllers. |
Pinout & Package
MC9S08DN32AMLF is packaged in a 48-pin LQFP (7×7 mm, 0.5 mm pitch), with 53 general-purpose I/O pins and 1 dedicated input-only pin. All I/O pins support configurable pull devices, hysteresis, slew rate, and drive strength; 24 pins support edge-selectable interrupts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VSS | Power supply and ground | Dual power domains: VDD (core/digital I/O), VSS (digital ground); separate analog supply (VDDAD/VSSAD) required for ADC/ACMP noise immunity. |
| VREFH / VREFL | Analog reference inputs | External or internal (bandgap) reference selection for ADC and ACMP; enables ratiometric measurements and stable threshold detection. |
| XTAL / EXTAL | Crystal oscillator terminals | Supports 1–16 MHz crystal or ceramic resonator; feeds MCG module for precise system clock generation and RTC timebase. |
| PTA0–PTA7 | Port A I/O | 8-bit general-purpose port with interrupt capability on all pins; used for GPIO, SCI TX/RX, SPI signals, or TPM channels depending on multiplexing configuration. |
| PTB0–PTB7 | Port B I/O | 8-bit port supporting ADC channel inputs (AD0–AD7), I²C SCL/SDA, and TPM1/TPM2 functions - enables compact analog + communication integration. |
| RESET | Active-low reset input | Asynchronous reset with internal pull-up; accepts external reset supervisor or microcontroller-initiated reset via COP watchdog timeout. |
| BKGD/MS | Background debug / mode select | Single-wire debug interface pin; also selects active background mode during reset - eliminates need for JTAG header in production PCB layout. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated LIN 2.0 SCI | Enables direct connection to automotive LIN networks without external transceiver for slave-node applications like mirror controls or seat position sensors. |
| In-circuit programmable EEPROM | 2 KB EEPROM with 4-byte dual-page erase allows fine-grained nonvolatile storage of calibration data, fault logs, or user settings without flash wear leveling overhead. |
| Real-time interrupt in Stop mode | 1-kHz internal oscillator drives RTC wake-up events during Stop2/Stop3, enabling periodic sensor polling or CAN/LIN message scheduling without external timing components. |
| Factory-trimmed internal reference clock | MCG's internal reference clock trimmed at factory and stored in flash; achieves ±1.5% FLL accuracy across temperature - reduces BOM cost vs. external crystal in non-RTC applications. |
| ADC with temperature sensor | On-die temperature sensor channel (AD15) provides system thermal monitoring with ±3°C accuracy - supports thermal derating in motor drivers or power supplies. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S9S08DN32F1MLF | Same die, but with Flash security enabled by default and different mask set revision; identical pinout, memory map, and peripheral set. | No functional difference in LIN, ADC, or timer usage; differs only in flash security boot behavior and factory programming defaults. | Select S9S08DN32F1MLF when flash security enforcement is required at power-on; otherwise MC9S08DN32AMLF offers standard unsecured boot for development and field updates. |
| MC9S08DZ32CLC | 44-pin LQFP package; same 32 KB flash, 2 KB RAM/EEPROM, and HCS08 core, but lacks RTC and has only one TPM (6-channel) instead of two. | Not suitable for RTC-dependent applications (e.g., scheduled wake-up); fewer I/O and no second TPM limits multi-motor or dual PWM channel use. | Choose MC9S08DZ32CLC only for space-constrained designs where RTC and dual TPM are unnecessary and 44-pin footprint is preferred. |
Compared with S9S08DN32F1MLF and MC9S08DZ32CLC, the MC9S08DN32AMLF provides full RTC functionality, dual TPM modules, and standard flash security configuration - making it optimal for automotive body control modules requiring time-triggered operations and independent PWM outputs.

This frequency is achievable across the full industrial temperature range (–40°C to +105°C) when supplied with 2.7–5.5 V and using appropriate clock source configuration (e.g., MCG in PLL or FLL mode). The MC9S08DN32AMLF datasheet specifies timing parameters consistent with this performance under validated conditions.
Does the MC9S08DN32AMLF support LIN 2.0 protocol natively?
Yes, the MC9S08DN32AMLF includes a dedicated Serial Communications Interface (SCI1) that fully supports LIN 2.0 and SAE J2602 protocols. It provides hardware features including master extended break generation, slave extended break detection, wakeup on active edge, and automatic checksum calculation - enabling compliant LIN slave node implementation without external protocol assist hardware.
How much EEPROM does the MC9S08DN32AMLF have, and what are its erase characteristics?
The MC9S08DN32AMLF integrates 2 KB of on-chip EEPROM with 4-byte dual-page or 8-byte single-page erase sectors. It supports program and erase while executing flash code, and includes erase abort functionality. These characteristics allow reliable storage of calibration data, fault logs, or user preferences with minimal impact on real-time application execution.
What package type and pin count does the MC9S08DN32AMLF use?
The MC9S08DN32AMLF is supplied in a 48-pin low-profile quad flat-pack (LQFP) package measuring 7×7 mm with 0.5 mm lead pitch. This package provides 53 general-purpose I/O pins and 1 input-only pin, with 24 pins supporting configurable edge-selectable interrupts - matching mechanical and thermal requirements for automotive PCB layouts.
Can the MC9S08DN32AMLF operate in low-power modes with RTC functionality active?
Yes, the MC9S08DN32AMLF supports real-time interrupt generation during Stop2 and Stop3 modes using its on-chip 1-kHz low-power oscillator. This allows the RTC to maintain timekeeping and trigger wake-up events without external crystals or power supply changes - essential for battery-powered automotive modules requiring periodic sensor reads or scheduled communications.
