Product details
Overview
MC9S08DN16AMLF from NXP (formerly Freescale) is an 8-bit HCS08 microcontroller with 16 KB on-chip Flash, 2 KB RAM, and 2 KB in-circuit programmable EEPROM. It features a 40-MHz CPU core (20-MHz bus), 12-bit 16-channel ADC with temperature sensor, dual analog comparators, SCI supporting LIN 2.0/J2602, SPI, I²C, two TPM modules (6+2 channels), RTC, and real-time interrupt capability - deployed in automotive body control modules and industrial sensor nodes.
For engineers reviewing the MC9S08DN16AMLF datasheet, MC9S08DN16AMLF pinout, MC9S08DN16AMLF application, or MC9S08DN16AMLF equivalent, key selection criteria include Flash size (16 KB), EEPROM endurance (100K erase/write cycles), 53 GPIO with configurable slew rate and hysteresis, and support for LIN-compliant serial communication in low-power stop modes.
Technical Context
The MC9S08DN16AMLF implements the S08CPUV3 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-based clock synthesis with internal reference trimming and external crystal support (1–16 MHz or 31.25 kHz–38.4 kHz).
Peripherals are tightly integrated: the 12-bit ADC achieves 2.5 μs conversion time with automatic compare and bandgap reference; TPM1 offers 6-channel input capture/output compare/PWM; RTC uses either external 32.768 kHz crystal or internal 1-kHz oscillator for wake-up scheduling without external components.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S9S08DN16F1MLF | Same die, newer mask set; adds MSCAN module (CAN 2.0B compliant) and updated MCG trim algorithm | Required where CAN bus connectivity is needed; not suitable for LIN-only or cost-sensitive LIN-only designs | Select S9S08DN16F1MLF only if CAN interface is mandatory; otherwise MC9S08DN16AMLF offers lower BOM cost and identical LIN/peripheral feature set |
| MC9S08DZ128MLH | 128 KB Flash, 8 KB RAM, enhanced ADC (16-bit optional), additional SCI/I²C channels, 64-pin LQFP | Targeted at scalable platforms requiring future firmware expansion or higher-resolution sensing; larger footprint and higher power | Choose MC9S08DZ128MLH when >16 KB Flash or >2 KB RAM is required; MC9S08DN16AMLF remains optimal for fixed-function LIN nodes with tight cost/power constraints |
Compared with S9S08DN16F1MLF and MC9S08DZ128MLH, the MC9S08DN16AMLF delivers the minimal viable feature set for LIN-based automotive body electronics - balancing Flash density, peripheral count, package size, and legacy toolchain compatibility without over-provisioning resources.

FAQ
What is the maximum operating frequency of the MC9S08DN16AMLF CPU core?
The MC9S08DN16AMLF CPU core operates at up to 40 MHz, delivering a 20-MHz bus frequency. This performance level is achieved using the on-chip Multi-Purpose Clock Generator (MCG) in PLL or FLL mode, with support for external crystals up to 16 MHz or internal trimmed reference clock. The MC9S08DN16AMLF maintains full functionality across its specified voltage (2.7–5.5 V) and temperature (−40°C to +105°C) ranges at this speed.
Does the MC9S08DN16AMLF include a hardware watchdog timer?
Yes, the MC9S08DN16AMLF integrates a Computer Operating Properly (COP) watchdog timer with configurable timeout and dual clock source options: it can run from either the main bus clock or a dedicated 1-kHz internal clock source. This ensures reliable system recovery even during clock failure or severe software lockup. The COP module is enabled by default after reset and must be serviced regularly in firmware to prevent unintended reset of the MC9S08DN16AMLF.
Can the MC9S08DN16AMLF execute code while erasing or programming its EEPROM?
Yes, the MC9S08DN16AMLF supports program-and-erase-while-executing (PEWE) for both Flash and EEPROM memory. Its 2 KB EEPROM allows 4-byte dual-page or 8-byte single-page erase sectors, and the MC9S08DN16AMLF can continue executing instructions from Flash or RAM during EEPROM write/erase operations - enabling seamless data logging without halting real-time control tasks.
What LIN protocol versions does the MC9S08DN16AMLF SCI module support?
The MC9S08DN16AMLF SCI1 module natively supports LIN 2.0 and SAE J2602 protocols through hardware-assisted extended break generation and detection, automatic synchronization, and wakeup-on-active-edge functionality. These capabilities are implemented in silicon and require no bit-banging - ensuring deterministic timing and interoperability with standard LIN transceivers. The MC9S08DN16AMLF meets all physical layer and protocol timing requirements defined in LIN 2.0 specification.
Is the MC9S08DN16AMLF pin-compatible with other members of the DN-series like MC9S08DN32 or MC9S08DN48?
No, the MC9S08DN16AMLF is not pin-compatible with MC9S08DN32 or MC9S08DN48. While all DN-series devices share the same 48-pin LQFP package option, pin assignments differ across memory variants due to distinct peripheral mappings and I/O multiplexing configurations. For example, certain ADC channels or TPM functions appear on different pins between the MC9S08DN16AMLF and higher-density variants - requiring PCB redesign for substitution.
