NXP Semiconductors MC9S08DV32AMLH

Overview

MC9S08DV32AMLH from NXP (formerly Freescale) is an 8-bit HCS08 microcontroller with 32 KB flash, 3 KB RAM, 53 GPIO pins, and integrated CAN 2.0A/B controller, ADC, SPI, I²C, SCI, TPM, and RTC - designed for automotive body electronics and industrial control systems requiring robust real-time communication and low-power operation.

For engineers reviewing the MC9S08DV32AMLH datasheet, MC9S08DV32AMLH pinout, MC9S08DV32AMLH application, or MC9S08DV32AMLH equivalent, key selection criteria include flash size, CAN protocol support, 12-bit ADC resolution, stop-mode power consumption, and LQFP-48 package compatibility with automotive-grade temperature range (−40°C to +105°C).

Technical Context

The MC9S08DV32AMLH implements the HCS08 CPU core running at up to 40 MHz (20 MHz bus), supporting 32 interrupt/reset sources and BGND debug instruction. Its Multi-Purpose Clock Generator (MCG) provides FLL/PLL modes with internal reference trimming and external crystal support from 1 MHz to 16 MHz.

On-chip peripherals include a 16-channel 12-bit ADC with 2.5 µs conversion time and temperature sensor, two analog comparators, MSCAN module with five receive buffers and programmable identifier filters (2×32-bit, 4×16-bit, or 8×8-bit), and dual SCI interfaces compliant with LIN 2.0 and SAE J2602 protocols.

Key Specifications

FAQ

What is the maximum operating frequency of the MC9S08DV32AMLH CPU core?

The MC9S08DV32AMLH CPU core operates at up to 40 MHz, with a corresponding 20 MHz bus frequency. This timing is achieved using the on-chip Multi-Purpose Clock Generator (MCG) in PLL or FLL mode, and is validated across the full −40°C to +105°C temperature range specified for the MC9S08DV32AMLH device.

Does the MC9S08DV32AMLH support CAN FD or only classical CAN?

The MC9S08DV32AMLH supports only Classical CAN (ISO 11898-1, CAN 2.0A/B) with standard and extended identifiers, remote frames, and five receive buffers. It does not implement CAN FD features such as flexible data-rate, larger payloads, or CRC enhancements - those capabilities require newer S32K or MPC5xxx families beyond the MC9S08DV32AMLH architecture.

How much SRAM is available on the MC9S08DV32AMLH, and is it retained in low-power modes?

The MC9S08DV32AMLH includes 3 KB of on-chip SRAM. This memory is fully retained in Wait mode and both Stop2 and Stop3 modes, provided VDD remains within specification. Retention is confirmed in the MC9S08DV60 Series Data Sheet Rev 3, Section 3.6.3, which specifies that RAM contents persist during all supported low-power states of the MC9S08DV32AMLH.

What debug interface does the MC9S08DV32AMLH use, and what hardware is required?

The MC9S08DV32AMLH uses a single-wire background debug (BDM) interface via the BKGD/MS pin. No JTAG header is needed; only a compatible BDM pod (e.g., PE Micro Cyclone or Segger J-Link with BDM firmware) and a simple 6-pin ribbon cable are required to perform full flash programming, breakpoint debugging, and real-time register inspection on the MC9S08DV32AMLH.

Is the internal temperature sensor on the MC9S08DV32AMLH factory-calibrated, and how is its value accessed?

Yes, the internal temperature sensor on the MC9S08DV32AMLH is factory-calibrated and accessible as ADC channel ADP16 (or AD16 depending on configuration). Its output is referenced to the internal bandgap voltage, and raw ADC readings must be converted using coefficients stored in flash memory - details are provided in Section 10.1.5 of the MC9S08DV60 Series Data Sheet Rev 3 applicable to the MC9S08DV32AMLH.
