NXP Semiconductors MC9S08DV128MLL

Overview

MC9S08DV128MLL from NXP Semiconductors (formerly Freescale) is an 8-bit HCS08 microcontroller with 128 KB on-chip FLASH, 6 KB RAM, and integrated MSCAN, dual SCI, dual SPI, dual IIC, three TPM modules, 12-bit ADC, and real-time counter. It operates at up to 40 MHz CPU / 20 MHz bus frequency and supports multiple low-power stop/wait modes. It is used in automotive body control modules requiring CAN communication, sensor interfacing, and deterministic real-time response.

For engineers reviewing the MC9S08DV128MLL datasheet, MC9S08DV128MLL pinout, MC9S08DV128MLL application, or MC9S08DV128MLL equivalent, key selection criteria include its 100-pin LQFP package, 5 V tolerant I/O, internal bandgap reference (1.18–1.21 V), PLL/FLL clock generation with external crystal support up to 16 MHz, and single-wire background debug interface.

Technical Context

The MC9S08DV128MLL implements the HCS08 CPU core with HC08 instruction set extension, supporting up to 32 interrupt/reset sources and BGND instruction for debugging. Its Multi-Purpose Clock Generator (MCG) provides FEI, FEE, FBE, PEE, and BLPE modes with nonvolatile trim (0.2% resolution, ±1.5% tolerance over temperature) and DIV32/DRS/DMX32 configuration for precise frequency synthesis.

Peripherals include a 24-channel 12-bit ADC with 2.5 µs conversion time and internal temperature sensor, two analog comparators with bandgap reference option, and MSCAN compliant with ISO 11898-1 (CAN 2.0A/B). The device lacks on-chip EEPROM - unlike the DZ-series variants - and uses FLASH-based data storage with sector erase capability.

Key Specifications

Pinout & Package

MC9S08DV128MLL is housed in a 100-pin low-profile quad flat-pack (LQFP) package, 14 mm × 14 mm, with 0.5 mm pitch and exposed thermal pad. Pin assignments follow Freescale's standardized HCS08 pinout layout, with dedicated VDD/VSS pairs distributed across corners and edges for noise reduction and power integrity.

Compared with MC9S08DZ128MLL, the MC9S08DV128MLL omits on-chip EEPROM but retains identical FLASH size, clock architecture, and CAN/ADC performance - making it optimal for cost-sensitive body electronics where parameters are stored in FLASH. Versus S9S08DZ128F2MLL, it lacks AEC-Q100 Rev G qualification and extended temperature support, limiting use to ambient-rated modules.

FAQ

What is the maximum operating frequency of the MC9S08DV128MLL CPU and bus?

The MC9S08DV128MLL features an HCS08 CPU core rated for up to 40 MHz operation, with a corresponding maximum bus frequency of 20 MHz. This timing is achieved using the on-chip Multi-Purpose Clock Generator (MCG) in PEE mode, where the PLL multiplies a 1–2 MHz reference (derived from an external crystal via RDIV/DIV32) to produce the system clock. The MC9S08DV128MLL datasheet specifies these values under DC characteristics at VDD = 5.0 V and TA = −40°C to 105°C.

Does the MC9S08DV128MLL include on-chip EEPROM memory?

No, the MC9S08DV128MLL does not include on-chip EEPROM. Unlike the MC9S08DZ128MLL variant, which integrates 2 KB of EEPROM, the MC9S08DV128MLL relies solely on its 128 KB FLASH memory for both program code and data storage. Data retention is managed via FLASH sector erase and write cycles, with wear-leveling implemented in firmware. This distinction is explicitly documented in the MC9S08DZ128 Series Data Sheet's memory comparison table.

What communication interfaces are supported by the MC9S08DV128MLL?

The MC9S08DV128MLL supports MSCAN (Controller Area Network, ISO 11898-1 compliant), two Serial Communications Interfaces (SCI) compatible with LIN 2.0 and SAE J2602, two Serial Peripheral Interfaces (SPI), and two Inter-Integrated Circuits (IIC) operating up to 100 kbps. All interfaces are fully integrated with DMA-capable registers and share the same 20 MHz bus clock domain. No external transceivers are required for basic SCI or SPI operation, though CAN physical layer drivers must be added externally.

What is the purpose of the DIV32 bit in the MCGC3 register of the MC9S08DV128MLL?

The DIV32 bit (bit 4) in the MCGC3 register of the MC9S08DV128MLL enables an additional divide-by-32 factor applied to the external reference clock before it enters the FLL when the RANGE bit is set (high-frequency crystal mode). It must be cleared when PLLS = 1 (i.e., PLL selected), as stated in the MC9S08DZ128 Series Data Sheet Addendum Rev. 2. This ensures correct reference frequency division for stable FLL lock or proper PLL input scaling - critical for achieving accurate 16 MHz bus clocks from 8 MHz crystals.

How many I/O pins does the MC9S08DV128MLL provide, and what are their voltage tolerances?

The MC9S08DV128MLL provides up to 87 general-purpose I/O pins and one input-only pin, all configured in its 100-pin LQFP package. All digital I/O pins are 5 V tolerant, meaning they accept input signals up to 5.5 V regardless of VDD level (within specified operating range), simplifying interface with legacy 5 V sensors and actuators. Input hysteresis and configurable pull devices are available on every pin, and output drive strength/slew rate can be adjusted per port to reduce EMI in noisy automotive environments.
