Product details
Overview
S9S08DZ48F2MLF from NXP Semiconductors (formerly Freescale) is an 8-bit HCS08 microcontroller designed for automotive and industrial control applications. It features a 40-MHz CPU core (20-MHz bus), 48 KB on-chip flash memory, 2 KB EEPROM, and 4 KB RAM. Integrated peripherals include MSCAN v2.0B, dual SCI with LIN 2.0 support, 24-channel 12-bit ADC, two analog comparators, and RTC with low-power oscillator.
For engineers reviewing the S9S08DZ48F2MLF datasheet, S9S08DZ48F2MLF pinout, S9S08DZ48F2MLF application, or S9S08DZ48F2MLF equivalent, key selection criteria include CAN 2.0B compliance, in-circuit programmable EEPROM with erase abort, single-wire background debug interface, and dual low-power stop modes with real-time interrupt wake-up capability.
Technical Context
The S9S08DZ48F2MLF implements the HCS08 CPU core with HC08 instruction set extension including BGND, supporting up to 32 interrupt/reset sources. Its Multi-Purpose Clock Generator (MCG) provides FLL and PLL modes with factory-trimmed internal reference clock and ±1.5% frequency stability over temperature.
On-chip system protection includes COP watchdog with dual clock source options (1 kHz internal or bus clock), low-voltage detect with configurable trip points, illegal opcode/address detection, and flash block protection. Peripheral integration centers on deterministic real-time control: MSCAN supports five receive buffers with FIFO and flexible identifier filtering (2×32-bit, 4×16-bit, or 8×8-bit), while the 12-bit ADC delivers 2.5 μs conversion time with automatic compare and integrated temperature sensor.

FAQ
What is the maximum operating frequency of the S9S08DZ48F2MLF CPU core?
The S9S08DZ48F2MLF CPU core operates at up to 40 MHz, with a corresponding 20 MHz bus frequency. This timing is achieved using the on-chip Multi-Purpose Clock Generator (MCG) in PLL or FLL mode, supporting precise timing requirements for real-time control loops and communication protocols like CAN and LIN. The S9S08DZ48F2MLF maintains this performance across its specified industrial temperature range (–40°C to +105°C) and supply voltage (2.7–5.5 V).
Does the S9S08DZ48F2MLF include integrated CAN controller hardware?
Yes, the S9S08DZ48F2MLF integrates a Freescale Controller Area Network (MSCAN) module compliant with ISO 11898-1 (CAN 2.0A/B). It supports standard and extended data frames, remote frames, five receive buffers with FIFO storage, and programmable identifier acceptance filters (configurable as 2×32-bit, 4×16-bit, or 8×8-bit). This hardware implementation offloads protocol handling from the CPU, ensuring deterministic timing for automotive network communication.
What debug interface does the S9S08DZ48F2MLF support?
The S9S08DZ48F2MLF supports a single-wire background debug (BDM) interface via the BKGD/MS pin. This interface enables full in-circuit emulation (ICE), real-time bus capture, flash programming, and breakpoint debugging without requiring additional pins or external debug adapters. The S9S08DZ48F2MLF uses this interface for both development and field firmware updates, maintaining compatibility with standard Freescale/NXP BDM tools and IDEs.
Can the S9S08DZ48F2MLF operate in low-power modes while maintaining real-time wake-up capability?
Yes, the S9S08DZ48F2MLF supports two very low-power stop modes (Stop2 and Stop3) and a reduced-power wait mode, all featuring a dedicated real-time interrupt (RTI) that operates from an on-chip 1 kHz low-power oscillator. This allows the S9S08DZ48F2MLF to wake autonomously at precise intervals without external components-critical for battery-powered telematics or periodic sensor sampling in automotive sleep modes.
How much EEPROM memory is available on the S9S08DZ48F2MLF, and what are its key endurance features?
The S9S08DZ48F2MLF includes 2 KB of on-chip EEPROM with in-circuit programmability. It supports 8-byte single-page or 4-byte dual-page erase sectors, program and erase while executing flash code, and erase abort functionality to prevent data corruption during unexpected power loss. These features make the S9S08DZ48F2MLF suitable for storing calibration data, configuration parameters, and event logs in automotive and industrial applications requiring nonvolatile memory with high write-cycle endurance.
