Product details
Overview
S9S08SG16E1CTGR from NXP Semiconductors (formerly Freescale) is an 8-bit HCS08 microcontroller with 16 KB on-chip 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 automotive body electronics and industrial control applications.
For engineers reviewing the S9S08SG16E1CTGR datasheet, S9S08SG16E1CTGR pinout, S9S08SG16E1CTGR application, or S9S08SG16E1CTGR equivalent, key selection criteria include Flash size (16 KB), TSSOP-16 package, 22 GPIOs, stop3 mode operation for ultra-low-power wake-up, and AEC-Q100 qualification suitability for automotive environments.
Technical Context
The S9S08SG16E1CTGR implements the HCS08 CPU core with HC08 instruction set extension, featuring a frequency-locked loop (FLL)-based Internal Clock Source (ICS) supporting 2–20 MHz bus frequencies. Its memory architecture includes 16 KB of on-chip Flash with block protection, 1 KB RAM, and nonvolatile register space for trimming and configuration.
Peripherals are tightly coupled to the CPU via a unified memory map: the 16-channel 10-bit ADC supports temperature sensor and internal bandgap reference; dual 2-channel TPM modules provide input capture, output compare, and PWM; and the real-time counter (RTC) runs in all modes-including stop3-using a dedicated 1 kHz low-power oscillator.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC9S08SG32E1CTGR | 32 KB Flash, identical peripheral set, same 16-pin TSSOP package and pinout | Higher Flash capacity supports larger firmware images and bootloader + application separation | Select when future firmware expansion or secure OTA updates require >16 KB code space |
| S9KEAZ128AMLH | Kinetis E-series ARM Cortex-M0+ core, 128 KB Flash, 16 KB RAM, enhanced analog and timing peripherals | Higher performance, richer peripheral set, and modern toolchain support-but requires PCB redesign due to different pin count and package (LQFP-64) | Choose for new designs needing scalable performance, CAN interface, or long-term roadmap alignment beyond 8-bit architecture |

FAQ
What is the maximum bus frequency supported by the S9S08SG16E1CTGR?
The S9S08SG16E1CTGR supports a maximum bus frequency of 40 MHz when operating within its specified voltage and temperature range. This is achieved using the internal clock source (ICS) with frequency-locked loop (FLL) and appropriate external crystal or internal reference trimming. The actual achievable frequency depends on supply voltage and ambient temperature, with derating above 125°C per datasheet specifications.
Does the S9S08SG16E1CTGR include hardware security features?
Yes, the S9S08SG16E1CTGR includes on-chip security circuitry that prevents unauthorized access to Flash and RAM contents via the background debug interface or mass erase commands. This is implemented through nonvolatile protection bits (NVOPT and NVPROT) and lock bits that disable read-out once programmed. Security activation is irreversible and must be configured during firmware development.
Can the S9S08SG16E1CTGR operate in ultra-low-power modes with peripherals active?
Yes, the S9S08SG16E1CTGR supports Stop3 mode, where the CPU and most peripherals halt while the real-time counter (RTC), analog comparator (ACMP), and certain wakeup sources remain active. In this mode, typical current consumption is less than 1 µA, enabling battery-operated applications with long standby life and deterministic wake-up intervals using the internal 1 kHz oscillator.
What analog peripherals are integrated into the S9S08SG16E1CTGR?
The S9S08SG16E1CTGR integrates a 16-channel, 10-bit successive approximation register (SAR) ADC with 2.5 µs conversion time, internal temperature sensor, and internal bandgap reference channel. It also includes two analog comparators (ACMP) with selectable interrupt on rising/falling/both edges, optional routing to TPM for hardware-triggered actions, and comparison against fixed internal bandgap voltage.
Is the S9S08SG16E1CTGR pin-compatible with other devices in the MC9S08SGxx family?
Yes, the S9S08SG16E1CTGR is pin-compatible with the MC9S08SG32E1CTGR in the 16-pin TSSOP package, sharing identical pin assignments, electrical characteristics, and peripheral mapping. Both devices use the same silicon die with differing Flash sizes, enabling direct substitution where firmware fits within 16 KB without layout changes.
