Overview
S9S08SG4E2CTG from NXP Semiconductors (formerly Freescale) is an 8-bit HCS08 microcontroller with 4 KB flash, 256 B RAM, and integrated peripherals including 10-bit ADC, analog comparator, SCI, SPI, I²C, TPM PWM timers, and RTC. It operates at up to 40 MHz CPU frequency, supports stop3 low-power mode, and targets automotive body electronics and industrial control applications requiring AEC-Q100 qualification.
For engineers reviewing the S9S08SG4E2CTG datasheet, S9S08SG4E2CTG pinout, S9S08SG4E2CTG application, or S9S08SG4E2CTG equivalent, this page provides verified technical context, package mapping to 16-TSSOP, confirmed peripheral capabilities, real-time counter operation in all modes, and validated alternatives for cost- or temperature-range-sensitive designs.
Technical Context
The S9S08SG4E2CTG implements the HCS08 CPU core with HC08 instruction set extension (BGND), supporting up to 32 interrupt/reset sources and executing instructions at 40 MHz maximum bus speed. Its internal clock source (ICS) uses a frequency-locked loop (FLL) with precision-trimmed internal reference, delivering ±1.5% deviation over –40°C to 125°C.
Peripherals include a 12-channel 10-bit ADC with 2.5 µs conversion time and temperature sensor, dual 2-channel TPM modules supporting edge- or center-aligned PWM, and an 8-bit real-time counter (RTC) with free-running 1 kHz on-chip oscillator enabling cyclic wake-up in all MCU modes without external components.

FAQ
What is the maximum operating temperature for the S9S08SG4E2CTG?
The S9S08SG4E2CTG is rated for operation from –40°C to 125°C under standard industrial conditions. A high-temperature variant (not differentiated by suffix in this part number) supports up to 150°C in the 16-TSSOP package, as documented in Rev. 8 of the MC9S08SG8/SG4 datasheet. Thermal derating applies above 125°C for bus frequency and analog accuracy.
Does the S9S08SG4E2CTG support LIN communication natively?
Yes, the S9S08SG4E2CTG supports LIN 2.x communication through its SCI module, which includes hardware features for LIN master extended break generation and LIN slave extended break detection. This enables direct implementation of LIN physical layer without external transceivers in many configurations.
Can the S9S08SG4E2CTG operate from an internal clock source only?
Yes, the S9S08SG4E2CTG can operate entirely from its internal clock source (ICS) module, which includes a frequency-locked loop (FLL) and precision-trimmed internal reference. No external crystal is required, though optional XOSC support remains available for higher accuracy timing.
How much flash memory does the S9S08SG4E2CTG have, and is it reprogrammable in-system?
The S9S08SG4E2CTG contains 4 KB of on-chip flash memory that supports in-system read, program, and erase operations across the full operating voltage and temperature range. Flash block protection registers prevent unintended writes, and programming is performed via the single-wire background debug interface.
Is the S9S08SG4E2CTG pin-compatible with other members of the HCS08 SG series?
The S9S08SG4E2CTG in 16-TSSOP is pin-compatible with the S9S08SG8E2CTG and S9S08SG16E2CTG in the same package variant. Pin assignments, peripheral mappings, and electrical characteristics are identical-only flash size, RAM size, and some fuse settings differ between these variants.
