NXP Semiconductors MC9S08GT60ACFDE

Overview

MC9S08GT60ACFDE from NXP Semiconductors (formerly Freescale) is an 8-bit HCS08 core microcontroller with 60 KB flash, 4 KB RAM, and integrated peripherals including dual SCI, SPI, I²C, 16-channel ADC, and two 16-bit timer/PWM modules. It operates at up to 40 MHz bus frequency, supports multiple low-power stop modes, and targets cost-sensitive industrial control and automotive body electronics applications.

For engineers reviewing the MC9S08GT60ACFDE datasheet, MC9S08GT60ACFDE pinout, MC9S08GT60ACFDE application, or MC9S08GT60ACFDE equivalent, key selection criteria include flash endurance (100k erase/write cycles), on-chip voltage regulator (2.7–5.5 V operation), background debug interface (BDM), QFN-48 package thermal performance, and compatibility with legacy HCS08 toolchains and development environments.

Technical Context

The MC9S08GT60ACFDE implements the S08CPUV2 core with 16-bit index register, 8-bit accumulator, and 16-level hardware stack. Its internal clock generator (S08ICGV2) supports FEE, FBE, FEI, and SCM modes with programmable PLL multiplication and crystal oscillator support down to 32 kHz.

Peripheral integration includes S08SCIV1 (dual SCI with LIN support), S08SPIV3, S08IICV1 (I²C master/slave), S08ATDV3 (10-bit ADC with 16 channels and 7 µs conversion), and S08TPMV1 (two independent 16-bit TPM modules with input capture, output compare, and edge-aligned PWM).

Key Specifications

Pinout & Package

FAQ

What is the maximum operating frequency of the MC9S08GT60ACFDE?

The MC9S08GT60ACFDE supports a maximum bus frequency of 40 MHz, achieved via its internal clock generator's FLL-engaged external clock (FEE) mode with appropriate crystal or external clock source. This allows sub-25 ns instruction cycle times for deterministic real-time control loops. The MC9S08GT60ACFDE datasheet specifies this limit across the full −40°C to +105°C temperature range and 2.7–5.5 V supply voltage.

Does the MC9S08GT60ACFDE include an integrated voltage regulator?

Yes, the MC9S08GT60ACFDE includes an on-chip linear voltage regulator that generates a stable 1.8 V core supply from the main VDD rail (2.7–5.5 V). This eliminates the need for an external core regulator in most designs and simplifies power sequencing. The regulator is enabled by default and can be disabled via the SOPT register if external 1.8 V regulation is preferred.

How many analog-to-digital converter channels does the MC9S08GT60ACFDE support?

The MC9S08GT60ACFDE integrates a 10-bit successive approximation ADC (S08ATDV3) with 16 selectable input channels (AD0–AD15), mapped across Port B and dedicated analog pins. Conversion time is 7 µs per sample, and the module supports hardware triggering from TPM, SCI, or software start - enabling precise synchronization in motor control or sensor acquisition applications.

What debug interface does the MC9S08GT60ACFDE use?

The MC9S08GT60ACFDE uses the Background Debug Mode (BDM) interface, implemented on the PTG0 pin as a single-wire, bidirectional serial protocol. It supports full-speed run/stop control, memory and register access, breakpoint setting, and flash programming without halting peripheral operation - all using standard Freescale/NXP BDM debuggers such as the DEMO9S08GB60 or standalone Multilink units.

Is the MC9S08GT60ACFDE pin-compatible with other HCS08 devices in the GT family?

The MC9S08GT60ACFDE shares the same 48-pin QFN package (98ASA00466D) and pin mapping with MC9S08GT32ACFDE and MC9S08GT16ACFDE, making it a drop-in upgrade path for flash capacity. However, it is not pin-compatible with GB-series or AC-series variants due to differences in peripheral assignment and power pin placement - always verify pin function tables in the respective datasheets before substitution.
