NXP Semiconductors MC9S08DV16ACLCR

Overview

MC9S08DV16ACLCR from NXP (formerly Freescale) is an 8-bit HCS08 microcontroller with 16 KB on-chip flash, 2 KB RAM, 40-MHz CPU (20-MHz bus), and integrated CAN 2.0A/B controller, ADC, and real-time counter - deployed in automotive body control modules and industrial sensor nodes requiring deterministic timing and robust communication.

For engineers reviewing the MC9S08DV16ACLCR datasheet, MC9S08DV16ACLCR pinout, MC9S08DV16ACLCR application, or MC9S08DV16ACLCR equivalent, key selection criteria include CAN protocol compliance, flash memory size, stop-mode power consumption, and background debug interface support for production firmware updates.

Technical Context

The MC9S08DV16ACLCR implements the S08CPUV3 core with HC08 instruction set extension (including BGND), supports up to 32 interrupt/reset sources, and uses a Multi-Purpose Clock Generator (MCG) with FLL and PLL modes - enabling precise clock synthesis from internal reference (factory-trimmed 31.25 kHz IRC) or external crystal (1–16 MHz).

Its peripheral suite includes a 12-bit, 16-channel ADC with 2.5 μs conversion time and internal temperature sensor, two analog comparators with bandgap reference option, and MSCAN module with five receive buffers, FIFO storage, and programmable identifier filters (2×32-bit, 4×16-bit, or 8×8-bit).

Key Specifications

Pinout & Package

FAQ

What is the maximum operating frequency of the MC9S08DV16ACLCR CPU core?

The MC9S08DV16ACLCR features an HCS08 CPU core rated for up to 40 MHz operation, delivering a 20-MHz bus clock frequency. This performance level supports real-time execution of CAN protocol stacks, sensor fusion algorithms, and PWM-based motor control loops without external acceleration. The MC9S08DV16ACLCR achieves this using its Multi-Purpose Clock Generator with FLL/PLL modes and factory-trimmed internal reference.

Does the MC9S08DV16ACLCR support CAN FD or only classical CAN 2.0?

The MC9S08DV16ACLCR implements the MSCAN v1 module compliant exclusively with CAN 2.0A/B (ISO 11898-1), supporting standard and extended identifiers, remote frames, and error confinement - but not CAN FD features such as variable bit rates or extended data length. Its CAN controller lacks the baud rate switching and CRC enhancements required for CAN FD, and no revision or erratum extends this capability to the MC9S08DV16ACLCR.

What package type and pin count does the MC9S08DV16ACLCR use?

The MC9S08DV16ACLCR is supplied in a 48-pin LQFP (low-profile quad flat-pack) package measuring 7×7 mm, with 53 general-purpose I/O pins and one dedicated input-only pin. This variant maps to the "CLCR" suffix per Freescale's ordering nomenclature and aligns with mechanical drawings in Appendix C of the MC9S08DV60 Series Data Sheet Rev 3.

How much RAM and flash memory does the MC9S08DV16ACLCR include?

The MC9S08DV16ACLCR integrates 16 KB of on-chip flash memory and 2 KB of RAM. Flash supports read/program/erase across full voltage and temperature ranges, with block protection and security features. RAM is used for variables, stack, and peripheral buffers - sufficient for lightweight CAN node firmware with ADC sampling and real-time scheduling.

Is the MC9S08DV16ACLCR pin-compatible with other members of the DV-series like MC9S08DV32ACLCR?

Yes - the MC9S08DV16ACLCR shares identical 48-pin LQFP packaging, pin assignment, and electrical characteristics with the MC9S08DV32ACLCR and MC9S08DV48ACLCR. All DV-series variants in the 48-pin CLCR package maintain full pin-to-pin compatibility, allowing hardware reuse across firmware variants differentiated only by flash size and minor mask-set revisions.
