NXP Semiconductors MC9S08DZ96MLL

Overview

MC9S08DZ96MLL from NXP (formerly Freescale) is an 8-bit HCS08 microcontroller with 96 KB flash, 6 KB RAM, and 2 KB EEPROM, featuring integrated CAN 2.0A/B controller, 12-bit ADC, dual SCI/LIN, dual SPI, dual I²C, and real-time counter - used in automotive body control modules and industrial sensor nodes.

For engineers reviewing the MC9S08DZ96MLL datasheet, MC9S08DZ96MLL pinout, MC9S08DZ96MLL application, or MC9S08DZ96MLL equivalent, key selection criteria include CAN protocol compliance, on-chip EEPROM endurance (100k erase/write cycles), stop3-mode current (1.5 µA typical), and background debug interface compatibility with S08 BDM tools.

Technical Context

The MC9S08DZ96MLL implements the HCS08 CPU core running at up to 40 MHz (20 MHz bus), supporting 32 interrupt/reset sources and BGND instruction for single-wire background debug. Its Multi-Purpose Clock Generator (MCG) provides FLL- and PLL-based clock synthesis with internal reference trimming (0.2% resolution).

Peripherals include a 24-channel 12-bit ADC with 2.5 µs conversion time and temperature sensor, two analog comparators operational in stop3 mode, and MSCAN with five receive buffers and programmable identifier filters (2×32-bit, 4×16-bit, or 8×8-bit).

Key Specifications

Pinout & Package

MC9S08DZ96MLL is housed in a 64-pin LQFP (10×10 mm, 0.5 mm pitch) package with 59 general-purpose I/O pins, 3 dedicated power/ground pins, and dedicated peripheral function pins including CANH/CANL, SCI0/SCI1, SPI0/SPI1, I²C0/I²C1, TPM channels, ADC inputs, and reset/debug signals.

FAQ

What is the maximum operating frequency of the MC9S08DZ96MLL CPU core?

The MC9S08DZ96MLL CPU core operates at up to 40 MHz, with a corresponding bus clock frequency of 20 MHz. This timing is achieved via the on-chip Multi-Purpose Clock Generator (MCG) in PLL or FLL mode, using either internal trimmed reference or external crystal/resonator input. The MC9S08DZ96MLL maintains full peripheral functionality at this speed, including CAN communication at 1 Mbps and ADC conversions within specification.

Does the MC9S08DZ96MLL support in-application programming (IAP) of its EEPROM?

Yes, the MC9S08DZ96MLL supports in-application programming of its 2 KB EEPROM, allowing firmware to write and erase EEPROM sectors while executing from flash memory. It supports 8-byte single-page or 4-byte dual-page erase operations, with erase abort capability and automatic wear leveling managed by application code. The MC9S08DZ96MLL EEPROM is rated for 100,000 erase/write cycles and 10-year data retention at 85°C.

What low-power modes are available on the MC9S08DZ96MLL, and what is the typical current draw in stop3 mode?

The MC9S08DZ96MLL supports two very low-power stop modes (stop2 and stop3), plus reduced-power wait mode. In stop3 mode - the deepest sleep state - typical current consumption is 1.5 µA at 25°C and 3.3 V, with optional real-time interrupt wake-up using the internal 1 kHz oscillator. The MC9S08DZ96MLL retains RAM contents and allows wake-up via CAN, SCI, TPM, or pin interrupts, making it suitable for battery-powered CAN nodes.

Is the MC9S08DZ96MLL pin-compatible with other members of the HCS08 DZ series?

The MC9S08DZ96MLL is pin-compatible with the MC9S08DZ128MLL and MC9S08DZ60MLL in the same 64-pin LQFP package, sharing identical pin assignments for power, I/O, CAN, SCI, SPI, I²C, and debug signals. However, memory mapping and some peripheral register defaults differ; firmware must be validated for flash size, EEPROM presence, and RAM allocation when migrating to or from the MC9S08DZ96MLL.

What development tools are supported for debugging the MC9S08DZ96MLL?

The MC9S08DZ96MLL supports NXP's S08 BDM (Background Debug Mode) interface via the BKGD/MS pin, compatible with P&E Micro's USB-ML-12 and Cyclone Pro debug probes, as well as older Freescale DEMO9S08DZ60 evaluation boards. It enables single-wire in-circuit debugging, flash programming, real-time bus capture, and non-intrusive breakpoints - all without requiring additional debug pins or JTAG header. The MC9S08DZ96MLL does not support SWD or JTAG.
