NXP Semiconductors MC9S08DZ96CLL

Overview

MC9S08DZ96CLL from NXP Semiconductors (formerly Freescale) is an 8-bit HCS08 microcontroller with 96 KB on-chip FLASH, 6 KB RAM, and 2 KB EEPROM, designed for automotive body electronics and industrial control systems. It integrates MSCAN (CAN 2.0A/B), dual SCI with LIN 2.0 support, 24-channel 12-bit ADC, three TPM modules (6+2+4 channels), RTC, and a programmable Multi-Purpose Clock Generator supporting FEI/FEE/FBE/PEE modes.

For engineers reviewing the MC9S08DZ96CLL datasheet, MC9S08DZ96CLL pinout, MC9S08DZ96CLL application, or MC9S08DZ96CLL equivalent, key selection criteria include CAN interface capability, 12-bit ADC resolution with temperature sensor, bus frequency up to 20 MHz, low-voltage detection with interrupt/reset, and single-wire background debug support in constrained embedded designs.

Technical Context

The MC9S08DZ96CLL implements the HCS08 CPU core running at up to 40 MHz internal clock (20 MHz bus), with nonvolatile trim for internal reference (0.2% resolution, 1.5% tolerance over temperature). Its MCG supports FLL and PLL modes using external crystals (31.25 kHz–16 MHz) or square-wave inputs, with configurable RDIV and DIV32 dividers to meet precise reference frequency requirements (e.g., 1–2 MHz for PLL operation).

Peripherals include two analog comparators with bandgap reference input, dual I²C interfaces (100 kbps), dual SPIs with double-buffered TX/RX, and a real-time counter with 1 kHz low-power oscillator for wake-up without external components. The device supports two very low-power stop modes (Stop2/Stop3) and retains RTC and comparator functionality during Stop3 mode.

FAQ

What is the maximum bus frequency supported by the MC9S08DZ96CLL?

The MC9S08DZ96CLL supports a maximum bus frequency of 20 MHz, derived from its internal 40-MHz HCS08 CPU clock. This frequency is achieved in PEE (Phase-Locked Loop Enabled) mode using an external crystal and proper MCG configuration (e.g., 8 MHz crystal → 1 MHz reference → ×32 PLL multiplication = 32 MHz core clock → ÷2 = 16 MHz bus, or optimized settings yielding 20 MHz bus). The MC9S08DZ96CLL datasheet specifies 20 MHz as the rated maximum bus speed under full operating conditions.

Does the MC9S08DZ96CLL include a hardware CAN controller?

Yes, the MC9S08DZ96CLL integrates the MSCAN module, a fully compliant Controller Area Network controller supporting CAN protocol version 2.0A and 2.0B. It handles standard and extended data frames, supports remote frames, provides five receive buffers with FIFO storage, and features flexible identifier acceptance filtering (configurable as 2×32-bit, 4×16-bit, or 8×8-bit masks). The MC9S08DZ96CLL requires only an external CAN transceiver for physical layer interfacing.

What are the memory resources available on the MC9S08DZ96CLL?

The MC9S08DZ96CLL provides 96 KB of on-chip FLASH memory for program storage, 6 KB of RAM for runtime variables and stack, and 2 KB of EEPROM for nonvolatile data retention. The EEPROM supports 4-byte dual-page or 8-byte single-page erase operations and allows program/erase while executing FLASH code. All memory blocks feature hardware block protection to prevent accidental overwrite, and the MC9S08DZ96CLL supports vector redirection for bootloader implementations.

Can the MC9S08DZ96CLL operate in ultra-low-power modes?

Yes, the MC9S08DZ96CLL supports multiple low-power modes including Wait mode and two very low-power Stop modes (Stop2 and Stop3). In Stop3 mode, the CPU, most peripherals, and FLASH are disabled, yet the RTC, analog comparators, and COP watchdog remain active - enabling wake-up via RTC overflow, comparator output transition, or external interrupt. The MC9S08DZ96CLL maintains this capability across its full −40°C to +125°C automotive temperature range.

Is single-wire debug supported on the MC9S08DZ96CLL?

Yes, the MC9S08DZ96CLL includes a single-wire background debug interface accessible via the BKGD/MS pin (Pin 14). This interface enables non-intrusive debugging, flash programming, and real-time memory inspection without requiring dedicated JTAG pins. The MC9S08DZ96CLL also integrates on-chip in-circuit emulation (ICE) with real-time bus capture, allowing developers to trace instruction execution and peripheral interactions during live operation.
