Product details
Overview
S9S08SG16E1CTLR from NXP Semiconductors (formerly Freescale) is an 8-bit HCS08 microcontroller with 16 KB Flash, 1 KB RAM, 22 GPIOs, 10-bit ADC, dual TPM modules, and integrated I²C/SPI/SCI peripherals - designed for automotive body electronics, industrial control, and low-power sensor nodes.
For engineers reviewing the S9S08SG16E1CTLR datasheet, S9S08SG16E1CTLR pinout, S9S08SG16E1CTLR application, or S9S08SG16E1CTLR equivalent, key selection criteria include its -40°C to +125°C operating range, on-chip ICS with FLL-based clock generation, stop3 mode power consumption of 1.2 µA, 16-channel ADC with temperature sensor, and single-wire background debug interface.
Technical Context
The S9S08SG16E1CTLR implements the HCS08 CPU core running at up to 40 MHz (36 MHz above 125°C), supporting 32 interrupt/reset sources and HC08 instruction set extensions including BGND. Its internal clock source (ICS) uses a frequency-locked loop (FLL) with precision-trimmed internal reference enabling ±1.5% frequency deviation over –40°C to +125°C.
Peripherals include two 2-channel timer-pulse-width-modulator (TPM) modules supporting input capture, output compare, and edge- or center-aligned PWM; a 16-channel 10-bit ADC with 2.5 µs conversion time and internal bandgap reference; and analog comparators (ACMP) that operate in stop3 mode. The device supports LIN-compliant SCI with extended break generation/detection.

FAQ
What is the maximum operating frequency of the S9S08SG16E1CTLR?
The S9S08SG16E1CTLR supports a maximum bus frequency of 40 MHz at ambient temperatures from –40°C to +125°C. When operating above +125°C, the maximum bus frequency is derated to 36 MHz to maintain timing integrity and thermal reliability. This specification is guaranteed across the full voltage range (2.7–5.5 V) and validated per Freescale's Rev. 8 MC9S08SG32 datasheet.
Does the S9S08SG16E1CTLR support LIN communication?
Yes, the S9S08SG16E1CTLR supports LIN communication through its SCI module, which includes dedicated hardware for LIN master extended break generation and LIN slave extended break detection. This enables direct integration into automotive body networks without external LIN transceivers for basic node functionality, as confirmed in Section 14 of the MC9S08SG32 Rev. 8 datasheet.
What power-saving modes are available on the S9S08SG16E1CTLR?
The S9S08SG16E1CTLR offers three low-power modes: Wait mode, Stop2, and Stop3. Stop3 is the deepest, drawing only 1.2 µA typical while keeping the RTC active from its internal 1 kHz oscillator. Both ADC and ACMP remain operational in Stop3, allowing event-triggered wake-up from analog conditions - a capability verified in Chapter 3 and Appendix A of the official datasheet.
Is the S9S08SG16E1CTLR pin-compatible with the MC9S08SG32E1CTLR?
Yes, the S9S08SG16E1CTLR is pin-compatible with the MC9S08SG32E1CTLR in the 28-pin TSSOP package. Both share identical pin assignments, electrical characteristics, peripheral mappings, and memory map structure - differing only in Flash size (16 KB vs. 32 KB) and unimplemented memory region size, as documented in Figure 4-1 of the MC9S08SG32 Rev. 8 datasheet.
What debug interface does the S9S08SG16E1CTLR use?
The S9S08SG16E1CTLR uses a single-wire background debug (BDM) interface via the BKGD/MS pin. It supports in-circuit flash programming, real-time register inspection, and breakpoint debugging using standard Freescale/NXP BDM tools. The on-chip debug module includes two comparators and nine trigger modes, as detailed in Chapter 17 of the MC9S08SG32 Rev. 8 datasheet.
