S9S08QD2J1MSCR

Product Overview

NXP USA Inc. S9S08QD2J1MSCR is an 8-bit S08 microcontroller in an 8-SOIC surface-mount package. It operates at 16 MHz with an internal oscillator, provides 2KB of FLASH program memory, and includes 128 x 8 RAM. The device supports a 2.7 V to 5.5 V supply range, four I/O pins, four 10-bit analog-to-digital inputs, and built-in LVD, POR, PWM, and WDT functions. It is rated for -40°C to 125°C ambient operation.

Applications

• Embedded control modules with an 8-SOIC footprint and four I/O pins.
• Sensor acquisition using four 10-bit analog inputs.
• Simple PWM-driven output control in space-constrained designs.
• Basic supervisory timing with POR, LVD, and WDT functions.
• Low-pin-count 8-bit control nodes operating from 2.7 V to 5.5 V.

Design & Procurement Notes

Design considerations should account for the 2KB FLASH program memory and 128 x 8 RAM, which limit code and data footprint. The four I/O pins and four 10-bit analog inputs constrain sensor and output connectivity, while the 16 MHz internal oscillator sets the timing baseline. The 2.7 V to 5.5 V supply range and -40°C to 125°C ambient rating support wider operating conditions, but the 8-SOIC surface-mount package requires appropriate pad layout and thermal handling. LVD, POR, PWM, and WDT peripherals can reduce external circuitry for basic supervision and timing.
