NXP Semiconductors MC9S08DV128MLF

Overview

MC9S08DV128MLF from NXP Semiconductors (formerly Freescale) is an 8-bit HCS08 microcontroller with 128 KB on-chip FLASH, 6 KB RAM, and integrated CAN 2.0A/B controller, ADC, SPI, I²C, SCI, and TPM peripherals. It operates at up to 40 MHz CPU/20 MHz bus frequency, supports multiple low-power modes, and targets automotive body electronics and industrial control applications requiring robust communication and real-time signal processing.

For engineers reviewing the MC9S08DV128MLF datasheet, MC9S08DV128MLF pinout, MC9S08DV128MLF application, or MC9S08DV128MLF equivalent, key selection considerations include its 64-pin LQFP package, CAN protocol compliance, internal bandgap reference (1.18–1.21 V), 12-bit 24-channel ADC with 2.5 µs conversion time, and MCG clock generator supporting FEE/FBE/PEE modes with external crystal up to 16 MHz.

Technical Context

The MC9S08DV128MLF implements the HCS08 CPU core with HC08 instruction set extension, including BGND for single-wire background debug. Its Multi-Purpose Clock Generator (MCG) supports FEI, FEE, FBE, PEE, and BLPE modes, with PLL reference divider selectable via RDIV (÷2 to ÷1024) and DCO output range of 16–40 MHz depending on DRS/DMX32 settings.

Peripherals include two SCIs supporting LIN 2.0 and SAE J2602, one MSCAN module with five receive buffers and programmable identifier filters (2×32-bit, 4×16-bit, or 8×8-bit), and three TPM modules (6-, 2-, and 4-channel) supporting edge-aligned and center-aligned PWM with coherency-protected modulo registers.

Key Specifications

FAQ

What is the maximum external crystal frequency supported by the MC9S08DV128MLF?

The MC9S08DV128MLF supports external crystals up to 16 MHz in high-range oscillator mode (RANGE = 1, HGO = 1), as specified in Table A-11 of the MC9S08DZ128 Series Data Sheet Rev. 2. This requires proper RDIV and optional DIV32 configuration to ensure the resulting reference clock falls within the 1–2 MHz range needed for PLL operation in PEE mode. The 16 MHz limit applies only when HGO is set; with HGO = 0, the maximum is 8 MHz.

Does the MC9S08DV128MLF include on-chip EEPROM memory?

No, the MC9S08DV128MLF does not include on-chip EEPROM. Unlike the MC9S08DZ128MLF variant, which integrates 2 KB of EEPROM, the DV-series parts rely solely on FLASH for nonvolatile storage. Designers must implement FLASH-based emulation for parameter retention if EEPROM functionality is required. This distinction is explicitly noted in the memory comparison table on page 5 of the MC9S08DZ128 Series Data Sheet.

What debug interface does the MC9S08DV128MLF support?

The MC9S08DV128MLF supports a single-wire background debug (BDM) interface via the BKGD/MS pin (Pin 64). This interface enables full in-circuit debugging, flash programming, and real-time bus capture without requiring additional pins or JTAG hardware. It is compatible with standard Freescale/NXP BDM debuggers and integrated development environments such as CodeWarrior and S32DS.

Can the MC9S08DV128MLF operate in low-power stop modes while maintaining CAN bus activity?

Yes, the MC9S08DV128MLF supports CAN activity in Stop3 mode via the MSCAN module's automatic wakeup feature. When configured with the appropriate clock source (e.g., internal 1 kHz oscillator), the CAN controller can detect dominant bits on the bus and trigger a wakeup interrupt without CPU intervention. This capability is documented in Section 12.6.3 ("On-Chip Peripheral Modules in Stop Modes") of the MC9S08DZ128 Series Data Sheet.

What is the ADC reference voltage specification for the MC9S08DV128MLF?

The MC9S08DV128MLF features an internal bandgap voltage reference of 1.18–1.21 V (typical 1.20 V) at VDD = 5.0 V, as specified in Parameter 24 of Table A-6 (DC Characteristics) in the MC9S08DZ128 Series Data Sheet Rev. 2. This reference is factory-trimmed and temperature-compensated, enabling accurate 12-bit ADC conversions without external reference components across the full operating temperature range.
