MC9S08DN32MLF
MC9S08DN32MLF - 8-Bit 40MHz 32KB MCU | NXP
The NXP MC9S08DN32MLF is an 8-bit S08 microcontroller with a 40 MHz HCS08 core, 32 KB of Flash program memory, 1.5 KB of RAM, 39 I/O pins, and a 48-LQFP 7x7 mm package. It also provides a 16-channel 12-bit ADC, 1 KB EEPROM, connectivity including I2C, LINbus, SCI, and SPI, plus LVD, POR, PWM, and watchdog support. These verified values make it suitable for embedded control, sensing, communications, and industrial equipment.
An S08 microcontroller is an embedded-control member of the microcontroller hierarchy, combining a CPU core, nonvolatile firmware memory, volatile working memory, digital I/O, and specialized peripherals on one semiconductor. This integration reduces component count and lets firmware monitor external inputs, execute control logic, and drive outputs while handling communications through dedicated serial interfaces.
Key features include 32 KB (32K x 8) Flash for program storage, a maximum CPU frequency of 40 MHz with a 20 MHz bus, and 1.5K x 8 RAM for data and stack operations. The 12-bit ADC has 16 channels and a stated 2.5-second conversion time in the retrieved data. Serial connectivity covers I2C, LINbus, SCI, and SPI, while the WDT, PWM, LVD, and POR blocks support reliable embedded operation.
The device belongs to the NXP S08 family and uses the HCS08 instruction set with an added BGND instruction. Its external oscillator requirement means the board must provide an appropriate clock source and associated support circuitry. Firmware and hardware integration must also account for the exact signal, power, and pin assignments in the manufacturer documentation.
Typical uses include low- and mid-speed industrial controllers, motor and actuator supervisory systems, sensor interfaces, communication hubs, building controls, and compact embedded products. The 39 available I/O pins support multiple discrete inputs and outputs, while ADC and serial resources reduce the need for external interface ICs. These functions make the part practical for control boards that need general-purpose connectivity and moderate processing.
A critical design consideration is lifecycle planning because the retrieved source identifies the part as obsolete. Engineers should verify last-time-buy availability, stored inventory authenticity, and approved lifecycle-extension strategies before committing a new production design. Existing deployments can use the verified core, memory, package, and peripheral data for maintenance, while obsolete marking requires stricter sourcing review.
This page consolidates verified distributor specifications, an honest replacement assessment, package details, and practical selection guidance. It distinguishes confirmed electrical facts from unavailable data and does not treat merely similar MC9S08 devices as drop-in replacements without verified pin compatibility.
