NXP Semiconductors MC908GZ60VFAE

Overview

MC908GZ60VFAE from NXP (formerly Freescale) is an 8-bit HCS08 microcontroller featuring 60 KB on-chip Flash memory, 2 KB RAM, a 10-bit ADC with 24 input channels, integrated MSCAN08 controller, and dual TIM modules for motor control and timing-critical tasks. It operates at up to 40 MHz core frequency with PLL-based clock generation and supports LIN bus via ESCI module - used in automotive body electronics and industrial sensor nodes.

For engineers reviewing the MC908GZ60VFAE datasheet, MC908GZ60VFAE pinout, MC908GZ60VFAE application, or MC908GZ60VFAE equivalent, key selection criteria include Flash endurance (100k erase/write cycles), CAN 2.0A compliance, low-voltage inhibit (LVI) threshold of 2.7 V, and support for stop-mode current down to 1.5 µA - critical for battery-powered automotive modules requiring ASIL-B–aligned robustness.

Technical Context

The MC908GZ60VFAE implements the HCS08 CPU core with enhanced addressing modes and a 16-level hardware stack. Its Clock Generator Module (CGM) integrates a crystal oscillator, PLL with programmable multiplier (×1 to ×32), and automatic acquisition/lock logic enabling stable 40 MHz operation from a 4 MHz crystal.

Peripheral integration includes MSCAN08 (CAN 2.0A compliant with 32 message buffers), ESCI supporting LIN 2.0 master/slave, two independent 16-bit TIM modules with input capture/output compare and PWM generation, and a 24-channel 10-bit ADC with configurable sample-and-hold and scan sequencing.

Key Specifications

Pinout & Package

MC908GZ60VFAE is housed in a 64-pin LQFP package (10 mm × 10 mm, 0.5 mm pitch) with exposed thermal pad. Pin assignments follow standard HCS08 GZ-series layout, including dedicated CAN TX/RX pins (PTC6/CANTX, PTC7/CANRX), ESCI serial I/O (PTE0/TxD, PTE1/RxD), and ADC reference inputs (VREFH/VREFL).

FAQ

What is the maximum operating frequency of the MC908GZ60VFAE?

The MC908GZ60VFAE achieves a maximum core frequency of 40 MHz using its integrated PLL clock generator. This is derived from an external 4 MHz crystal oscillator multiplied by 10, with full operation guaranteed across the –40°C to +125°C temperature range and 2.7–5.5 V supply voltage. The PLL lock time is specified at ≤10 ms under nominal conditions, ensuring rapid wake-up from stop mode.

Does the MC908GZ60VFAE support CAN FD?

No, the MC908GZ60VFAE implements the MSCAN08 module compliant only with CAN 2.0A (11-bit identifiers, 1 Mbps max). It does not support CAN FD features such as flexible data-rate, extended identifiers, or payload lengths beyond 8 bytes. For CAN FD applications, consider NXP's S32K1xx series or standalone CAN FD controllers interfaced via SPI.

How many ADC channels does the MC908GZ60VFAE support, and what is their resolution?

The MC908GZ60VFAE integrates a single 10-bit successive-approximation ADC with up to 24 selectable analog input channels mapped across Ports A, B, G, and dedicated ADC pins. Conversion time is programmable from 1 µs to 16 µs per sample, and results can be left- or right-justified in the 16-bit data register. Input voltage range is 0–VREFH, with VREFH configurable externally or tied to VDD.

What debug interfaces are supported by the MC908GZ60VFAE?

The MC908GZ60VFAE supports background debug mode (BDM) via a single-wire interface using the BKGD pin (shared with Port D pin PTD6). This allows non-intrusive flash programming, real-time register inspection, and breakpoint debugging without halting peripheral operation. No JTAG or SWD support is provided - BDM is the sole standardized debug method for this HCS08 device.

Is the MC908GZ60VFAE pin-compatible with other devices in the GZ family?

Yes, the MC908GZ60VFAE shares identical pinout and package (64-pin LQFP) with MC908GZ48VFAE and MC908GZ32VFAE. Differences are limited to Flash size (60/48/32 KB) and RAM allocation (2 KB across all variants), allowing hardware design reuse and firmware scalability within the same PCB layout.
