Product details
Overview
S9S08SG16E1WTGR from NXP Semiconductors (formerly Freescale) is an 8-bit HCS08 microcontroller with 16 KB Flash, 1 KB RAM, and integrated peripherals including 10-bit ADC, dual TPM timers, SCI, SPI, I²C, ACMP, and RTC. It operates at up to 40 MHz bus frequency, supports -40°C to 125°C temperature range, and targets embedded control in automotive body electronics and industrial sensors.
For engineers reviewing the S9S08SG16E1WTGR datasheet, S9S08SG16E1WTGR pinout, S9S08SG16E1WTGR application, or S9S08SG16E1WTGR equivalent, key selection criteria include Flash size, stop-mode power consumption, on-chip debug interface, peripheral integration (especially ADC channel count and TPM PWM capability), and thermal rating for under-hood or industrial environments.
Technical Context
The S9S08SG16E1WTGR implements the HCS08 CPU core with BGND instruction support and handles up to 32 interrupt/reset sources. Its internal clock source (ICS) uses a frequency-locked loop (FLL) with precision-trimmed internal reference enabling ±1.5% deviation over -40°C to 125°C.
Memory architecture includes 16 KB of on-chip FLASH (with block protection and security circuitry), 1 KB RAM, and dedicated registers for real-time counter, low-voltage detection (LVD/LVW), and COP watchdog. Peripherals operate in Stop3 mode, supporting ultra-low-power wake-up via RTC, ACMP, or external pin interrupt.
