Product details
Overview
S9S08DN32F1MLH from NXP Semiconductors (formerly Freescale) is an 8-bit HCS08 microcontroller with 32 KB on-chip Flash, 2 KB RAM, and 2 KB EEPROM, operating at up to 40 MHz CPU / 20 MHz bus frequency. It integrates ADC12, dual analog comparators, SCI with LIN 2.0 support, SPI, I²C, two TPM modules, RTC, and real-time interrupt capability - deployed in automotive body control modules and industrial sensor nodes.
For engineers reviewing the S9S08DN32F1MLH datasheet, S9S08DN32F1MLH pinout, S9S08DN32F1MLH application, or S9S08DN32F1MLH equivalent, key selection criteria include Flash size (32 KB), 48-pin LQFP package, LIN-capable SCI interface, 12-bit ADC with temperature sensor, and dual low-power stop modes for battery-operated systems.
Technical Context
The S9S08DN32F1MLH implements the HCS08 CPU core with HC08 instruction set plus BGND, supporting up to 32 interrupt/reset sources. Its Multi-Purpose Clock Generator (MCG) provides FLL- and PLL-based clock synthesis with factory-trimmed internal reference and external crystal support (1–16 MHz).
On-chip peripherals include a 16-channel 12-bit ADC with 2.5 μs conversion time and automatic compare, two analog comparators with bandgap reference option, and SCI1 compliant with LIN 2.0 and SAE J2602 - enabling direct integration into automotive sub-networks without external protocol translators.
