Product details
Overview
MC9S08DZ32AMLC from NXP (formerly Freescale) is an 8-bit HCS08 microcontroller with 32 KB on-chip Flash, 4 KB RAM, and integrated CAN 2.0A/B controller, ADC, and real-time counter - designed for automotive body electronics and industrial control nodes requiring robust communication and low-power operation.
For engineers reviewing the MC9S08DZ32AMLC datasheet, MC9S08DZ32AMLC pinout, MC9S08DZ32AMLC application, or MC9S08DZ32AMLC equivalent, this page delivers verified specifications, package mapping to 48-pin LQFP (7×7 mm), functional peripheral details, and validated alternative options for CAN-enabled embedded control designs.
Technical Context
The MC9S08DZ32AMLC implements the HCS08 CPU core running at up to 40 MHz (20 MHz bus), supporting 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 from 1–16 MHz.
On-chip peripherals include a 24-channel 12-bit ADC (2.5 µs conversion), two analog comparators, dual SCI modules compliant with LIN 2.0 and SAE J2602, SPI, I²C, two TPM timers (6- and 2-channel), and a real-time counter with 1 kHz low-power oscillator - all operating across run, wait, and stop3 modes.

FAQ
What is the maximum operating frequency of the MC9S08DZ32AMLC CPU core?
The MC9S08DZ32AMLC features an HCS08 CPU core rated for up to 40 MHz operation, with a corresponding 20 MHz bus frequency. This timing is achievable under full voltage (4.5–5.5 V) and temperature (–40°C to +125°C) ranges as specified in the Freescale MC9S08DZ60 Series Data Sheet Rev. 4. The actual bus speed depends on the selected MCG mode and divider settings.
Does the MC9S08DZ32AMLC include a built-in CAN transceiver?
No, the MC9S08DZ32AMLC integrates only the MSCAN controller (protocol layer), not the physical CAN transceiver. External transceivers such as the TJA1040 or MC33886 must be used on the CANTX/CANRX pins to drive the CAN bus. This separation allows design flexibility in selecting transceivers optimized for voltage range, fault protection, or EMC performance.
How much EEPROM memory does the MC9S08DZ32AMLC provide, and what are its key usage characteristics?
The MC9S08DZ32AMLC includes 2 KB of in-circuit programmable EEPROM with 4-byte dual-page or 8-byte single-page erase sectors. It supports program-and-erase-while-executing Flash, enabling runtime parameter updates without halting application code. Erase operations can be aborted, and the EEPROM retains data for >10 years with >100,000 write cycles per sector.
What debug interface does the MC9S08DZ32AMLC support, and what hardware is required?
The MC9S08DZ32AMLC supports a single-wire background debug interface via the BKGD/MS pin. No dedicated debug header is needed - only a compatible debugger (e.g., P&E Multilink, SEGGER J-Link with SWD adapter) and a simple pull-up resistor on BKGD/MS for normal operation. On-chip ICE provides real-time bus capture without intrusive probes.
Is the MC9S08DZ32AMLC pin-compatible with other members of the DZ series, such as the MC9S08DZ48AMLC?
Yes, the MC9S08DZ32AMLC in the 48-pin LQFP package is pin-compatible with the MC9S08DZ48AMLC and MC9S08DZ16AMLC in the same package variant. All share identical pin assignments, electrical characteristics, and peripheral mappings - enabling hardware reuse across memory variants during design scaling or cost optimization.
