NXP Semiconductors S9S08DZ16F2MLC

Overview

S9S08DZ16F2MLC from NXP Semiconductors (formerly Freescale) is an 8-bit HCS08 microcontroller designed for automotive and industrial embedded control. It features a 20-MHz bus frequency, 16 KB on-chip Flash memory, 2 KB EEPROM, and 4 KB RAM. Integrated peripherals include MSCAN (CAN 2.0A/B), dual SCI with LIN 2.0 support, 24-channel 12-bit ADC, two analog comparators, and RTC - deployed in body control modules and sensor interface units.

For engineers reviewing the S9S08DZ16F2MLC datasheet, S9S08DZ16F2MLC pinout, S9S08DZ16F2MLC application, or S9S08DZ16F2MLC equivalent, this page delivers verified technical context, validated pin functions, real-world use cases, and confirmed alternative parts - all grounded in the MC9S08DZ60 Series Data Sheet Rev. 4 (June 2008) and NXP official documentation.

Technical Context

The S9S08DZ16F2MLC implements the HCS08 CPU core with BGND instruction support and handles up to 32 interrupt/reset sources. Its Multi-Purpose Clock Generator (MCG) supports FLL and PLL modes, with factory-trimmed internal reference clock and external crystal/resonator options (1–16 MHz or 31.25 kHz–38.4 kHz).

On-chip system protection includes COP watchdog with dual-clock source selection, low-voltage detect with configurable trip points, illegal opcode/address detection, and Flash block protection. Development is enabled via single-wire background debug and on-chip ICE with real-time bus capture.

FAQ

What is the maximum bus frequency supported by the S9S08DZ16F2MLC?

The S9S08DZ16F2MLC supports a maximum bus frequency of 20 MHz, derived from its 40-MHz HCS08 CPU core operating at double-speed instruction execution. This timing enables deterministic real-time response in automotive control loops and meets timing requirements for MSCAN bit rates up to 1 Mbps and SCI baud rates up to 115.2 kbps. The actual bus speed depends on MCG configuration and external clock source selection.

Does the S9S08DZ16F2MLC include a hardware CAN controller?

Yes, the S9S08DZ16F2MLC integrates a Freescale Controller Area Network (MSCAN) module compliant with CAN protocol version 2.0A and 2.0B. It supports standard and extended data frames, remote frames, five receive buffers with FIFO storage, and programmable identifier filtering (2×32-bit, 4×16-bit, or 8×8-bit). No external CAN controller is required for basic node implementation.

What are the memory resources available on the S9S08DZ16F2MLC?

The S9S08DZ16F2MLC provides 16 KB of on-chip Flash memory for program storage, 2 KB of EEPROM for nonvolatile data retention (with 4- or 8-byte erase granularity), and 4 KB of RAM for runtime variables and stack. Flash and EEPROM support in-circuit programming and erasure across full operating voltage and temperature ranges, enabling field firmware updates and parameter logging.

Can the S9S08DZ16F2MLC operate from an internal clock source only?

Yes, the S9S08DZ16F2MLC can operate using its internal reference clock (IRC), which is factory-trimmed and stored in Flash. The Multi-Purpose Clock Generator (MCG) supports FLL mode with internal reference, allowing full functionality-including MSCAN and SCI-without external crystals or resonators. However, CAN bit-rate accuracy requires tighter timing tolerance, so external crystal is recommended for CAN-heavy applications.

Is the S9S08DZ16F2MLC pin-compatible with other devices in the MC9S08DZ60 series?

The S9S08DZ16F2MLC shares the same 48-pin LQFP package and pinout as S9S08DZ32F2MLC and S9S08DZ48F2MLC, making it hardware-compatible within that package variant. It is not pin-compatible with the 64-pin or 32-pin variants of the DZ series. Firmware built for S9S08DZ16F2MLC will run on higher-memory variants without modification, subject to memory map alignment.
