NXP Semiconductors MC9S08DZ48AMLF

Overview

MC9S08DZ48AMLF from NXP Semiconductors (formerly Freescale) is an 8-bit HCS08 microcontroller with 48 KB on-chip flash, 4 KB RAM, and 2 KB EEPROM, featuring integrated MSCAN, dual SCI, SPI, I²C, 12-bit ADC, two analog comparators, and RTC - designed for automotive body electronics and industrial control applications requiring CAN communication and robust power management.

For engineers reviewing the MC9S08DZ48AMLF datasheet, MC9S08DZ48AMLF pinout, MC9S08DZ48AMLF application, or MC9S08DZ48AMLF equivalent, key selection criteria include CAN 2.0A/B compliance, 48 KB flash memory size, 40-MHz CPU clock (20-MHz bus), 53 GPIOs with configurable slew rate and pull devices, and support for Stop3/Stop2 low-power modes with real-time interrupt wake-up.

Technical Context

The MC9S08DZ48AMLF 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-based clock synthesis with internal reference trimming and external crystal support (1–16 MHz).

Peripherals are tightly integrated: MSCAN supports five receive buffers with programmable identifier filters (2×32-bit, 4×16-bit, or 8×8-bit); the 24-channel 12-bit ADC achieves 2.5 μs conversion time with temperature sensor and bandgap reference; TPM modules offer 6- and 2-channel PWM/capture with edge-aligned and buffered operation.

Key Specifications

FAQ

What is the maximum operating frequency of the MC9S08DZ48AMLF CPU core?

The MC9S08DZ48AMLF features an HCS08 CPU core with a maximum CPU clock frequency of 40 MHz, delivering a 20-MHz bus speed. This performance level supports real-time control tasks in automotive and industrial applications while maintaining low power consumption through dynamic clock gating and multiple stop modes. The MC9S08DZ48AMLF achieves this via its Multi-Purpose Clock Generator (MCG), which supports PLL and FLL modes with internal reference trimming.

Does the MC9S08DZ48AMLF support CAN FD or only classical CAN?

The MC9S08DZ48AMLF supports only classical CAN as defined in ISO 11898-1 (CAN 2.0A/B), not CAN FD. Its MSCAN module implements standard and extended data frames up to 8 bytes per frame, with five receive buffers and programmable identifier filters. CAN FD capabilities - including bit rate switching and payloads up to 64 bytes - are absent in the MC9S08DZ48AMLF architecture and were introduced in later NXP families such as S32K1xx.

How much EEPROM memory does the MC9S08DZ48AMLF include, and what are its erase characteristics?

The MC9S08DZ48AMLF includes 2 KB of on-chip EEPROM memory, organized for in-circuit programming with 4-byte dual-page or 8-byte single-page erase sectors. Erase operations can be aborted, and program/erase cycles occur independently of CPU execution - enabling data logging or parameter storage without halting application code. This EEPROM is distinct from flash and retains data across power cycles with guaranteed endurance of 100,000 write/erase cycles per sector.

What debug interface does the MC9S08DZ48AMLF use, and is JTAG supported?

The MC9S08DZ48AMLF uses a single-wire background debug (BDM) interface via the BKGD/MS pin - not JTAG. This interface enables full in-circuit emulation, real-time bus capture, and non-intrusive debugging without requiring additional pins or headers. JTAG is not implemented on the MC9S08DZ48AMLF; all development tools (e.g., P&E Multilink, OSJTAG) rely exclusively on the BDM protocol defined in the HCS08 architecture.

Is the MC9S08DZ48AMLF pin-compatible with other members of the DZ-series, such as MC9S08DZ60AMLF?

Yes, the MC9S08DZ48AMLF is pin-compatible with the MC9S08DZ60AMLF and MC9S08DZ32AMLF in the 48-pin LQFP package variant. All share identical pin assignments, electrical characteristics, and peripheral mappings - differing only in flash size (48 KB vs. 60 KB vs. 32 KB) and associated memory-related registers. This allows direct PCB reuse across variants when firmware size permits, simplifying design scaling and qualification.
