S9S08DZ48F2MLH - 8-Bit 40MHz 48KB Flash MCU | NXP
The NXP Semiconductors S9S08DZ48F2MLH is an 8-bit S08 CISC microcontroller operating up to 40 MHz, with 48 KB of flash memory and a 64-pin LQFP package. According to the verified NXP and DigiKey product data, the device is designed for automotive and industrial control systems requiring embedded communication, mixed-signal control, and robust peripheral integration. The verified distributor listing specifies 53 I/O, CANbus, I2C, LINbus, SCI, and SPI connectivity, while the NXP page identifies a LIN physical layer, 4 KB RAM, and an integrated LCD driver.
An 8-bit microcontroller is a compact embedded controller used to monitor inputs, execute control logic, and operate peripherals in systems such as automotive body modules, industrial equipment, consumer products, and sensor-control boards. The S08 architecture belongs to the broader microcontroller and embedded-processing hierarchy. Unlike a general-purpose microprocessor, this device integrates flash, RAM, communication interfaces, timers, analog functions, and debug support into one package.
The S9S08DZ48F2MLH combines 48 KB flash with 4 KB RAM and a 40 MHz maximum clock, providing useful memory capacity for protocol handling and control firmware. Its listed CANbus, I2C, LINbus, SCI, and SPI interfaces allow the controller to connect to automotive networks, sensors, transceivers, and external peripherals. The integrated LCD driver is also relevant to local human-interface displays, while the reported 1.5K x 8 EEPROM adds nonvolatile data storage.
The verified data identifies an automotive-qualified S08 family variant with an operating temperature range of -40 to +125 degrees Celsius. The 64-LQFP package provides 64 terminals and is suited to conventional surface-mount assembly. NXP’s product page describes the part as active, while distributor listings show availability and product documentation; exact current inventory, lead time, and price were not supplied as fixed values.
Typical uses include automotive body-control modules, LIN-connected sensors, CAN gateway equipment, industrial instrumentation, and compact display-control systems. Before designing a replacement, engineers should verify the exact pinout, clock configuration, memory map, peripheral set, electrical limits, and software compatibility from the manufacturer datasheet.
The most important design consideration is firmware and peripheral equivalence: a same-package device is not automatically a functional replacement if its pin multiplexing, timer resources, communication modules, or memory organization differs. This page combines verified source data with cautious qualification of every replacement claim.
Unlike a distributor listing that mainly provides catalog data, this page records the verified source set, distinguishes confirmed specifications from unavailable data, and applies strict drop-in criteria to proposed alternatives. Pricing, lead time, pin names, and unreported compliance claims are intentionally not inferred.
