Product details
Overview
S9S08EL16F1VTJR from NXP Semiconductors (formerly Freescale) is an 8-bit HCS08 microcontroller with 16 KB flash, 1 KB RAM, and integrated LIN/SCI/SPI/I²C peripherals. It features a 40-MHz CPU, on-chip EEPROM, real-time counter, 10-bit ADC with temperature sensor, and two analog comparators. Designed for automotive body electronics and industrial control nodes requiring LIN 2.0 compliance and low-power operation.
For engineers reviewing the S9S08EL16F1VTJR datasheet, S9S08EL16F1VTJR pinout, S9S08EL16F1VTJR application, or S9S08EL16F1VTJR equivalent, key selection criteria include LIN protocol support, stop3-mode current consumption (1.5 µA), 22 GPIO with configurable slew rate, and 28-TSSOP package compatibility with board-level space constraints.
Technical Context
The S9S08EL16F1VTJR implements the HCS08 CPU core with HC08 instruction set plus BGND, supporting up to 32 interrupt/reset sources. Its internal clock source (ICS) uses a frequency-locked loop (FLL) with precision-trimmed internal reference (±2% over voltage/temperature) to generate bus frequencies from 2–20 MHz.
Peripherals include a 16-channel 10-bit ADC (2.5 µs conversion), dual analog comparators with bandgap reference option, SLIC module compliant with LIN 2.0 and SAE J2602, and TPM modules supporting edge-aligned PWM. All critical analog and timing peripherals remain functional in stop3 mode.
