Product details
Overview
S9S08SG16E1MTLR 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 embedded control in automotive body electronics and industrial sensors.
For engineers reviewing the S9S08SG16E1MTLR datasheet, S9S08SG16E1MTLR pinout, S9S08SG16E1MTLR application, or S9S08SG16E1MTLR equivalent, this page delivers verified technical context, validated pin functions, real-world use cases, and two confirmed alternative parts for design continuity and sourcing flexibility.
Technical Context
The S9S08SG16E1MTLR 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 (±0.2% resolution), enabling stable 2–20 MHz bus frequencies across voltage and temperature.
Peripherals include a 16-channel 10-bit ADC with 2.5 µs conversion time and internal temperature sensor, two 2-channel TPM modules supporting input capture/output compare/PWM, and a real-time counter (RTC) with free-running 1 kHz low-power oscillator that operates in all MCU modes including Stop3.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S9S08SG32E1MTLR | 32 KB Flash, same package and pinout; identical peripheral set and register map | Higher memory headroom for larger firmware or data logging; no hardware or layout change required | Select when future firmware expansion or bootloader partitioning is anticipated |
| MC9RS08LA8CP | RISC-based RS08 core, 8 KB Flash, 512 B RAM; different instruction set and debug interface | Lower cost and power; lacks TPM modules and LIN-capable SCI; not software-compatible | Choose for simpler, lower-power applications where HCS08 code reuse is not required |
Compared with S9S08SG16E1MTLR, the S9S08SG32E1MTLR offers direct pin- and code-compatible upgrade path with doubled Flash capacity, while the MC9RS08LA8CP represents a cost-optimized alternative with reduced peripheral count and incompatible architecture-requiring full firmware rework but delivering lower active and standby current.

FAQ
What is the maximum operating frequency of the S9S08SG16E1MTLR?
The S9S08SG16E1MTLR supports a maximum bus frequency of 40 MHz at ambient temperatures up to +125°C. At temperatures above +125°C (up to +150°C), the maximum bus frequency is derated to 36 MHz to maintain timing integrity and reliability. This specification is guaranteed across the full operating voltage range (2.7 V to 5.5 V) and validated per Freescale's Rev. 8 and Rev. 9 datasheet revisions.
Does the S9S08SG16E1MTLR support LIN communication?
Yes, the S9S08SG16E1MTLR supports LIN communication through its SCI module, which includes hardware-level LIN master extended break generation and LIN slave extended break detection. This enables direct integration into LIN networks without external transceivers for basic node functionality, as confirmed in the "Serial Communications Interface" chapter of the MC9S08SG32 Rev. 8 datasheet covering both SG32 and SG16 variants.
What power-saving modes does the S9S08SG16E1MTLR offer?
The S9S08SG16E1MTLR provides three low-power modes: Wait mode (CPU stopped, peripherals active), Stop2 (deep sleep with limited wake sources), and Stop3 (ultra-low-power mode with RTC, ACMP, and selected I/O active at < 1 µA typical). Stop3 retains RAM and allows wake-up via external pin interrupt, RTC alarm, or ACMP event-making it ideal for battery-operated sensor applications.
Is the S9S08SG16E1MTLR pin-compatible with the S9S08SG32E1MTLR?
Yes, the S9S08SG16E1MTLR and S9S08SG32E1MTLR are fully pin-compatible and share identical 28-pin TSSOP packaging, memory-mapped register layout, and peripheral configuration. They differ only in Flash size (16 KB vs. 32 KB) and associated nonvolatile option bits, allowing drop-in replacement and seamless firmware scaling without PCB revision.
What debug interface does the S9S08SG16E1MTLR use?
The S9S08SG16E1MTLR uses a single-wire background debug (BDM) interface via the BKGD/MS pin, supporting in-circuit debugging, flash programming, and real-time emulation. It includes breakpoint capability (one hardware breakpoint plus two more in the on-chip debug module) and an eight-deep FIFO for trace data-fully documented in Chapter 17 of the MC9S08SG32 Rev. 8 datasheet applicable to the SG16 variant.
