Product details
Overview
S9S08SG8E2WTGR from NXP Semiconductors (formerly Freescale) is an 8-bit HCS08 microcontroller with 8 KB flash, 512 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 extended temperature operation.
For engineers reviewing the S9S08SG8E2WTGR datasheet, S9S08SG8E2WTGR pinout, S9S08SG8E2WTGR application, or S9S08SG8E2WTGR equivalent, key selection criteria include its 16-TSSOP package, -40°C to 150°C operating range, single-wire BDM debug interface, internal FLL clock source with ±1.5% accuracy over temperature, and peripheral support for LIN-compliant SCI and stop3-resident ADC/ACMP operation.
Technical Context
The S9S08SG8E2WTGR implements the HCS08 CPU core with HC08 instruction set extension (including BGND), supporting up to 32 interrupt/reset sources and two very low-power stop modes. Its internal clock source (ICS) uses a frequency-locked loop (FLL) trimmed for ±1.5% deviation from –40°C to 125°C and ±3% above 125°C, enabling bus frequencies from 2 MHz to 20 MHz.
Peripherals include a 12-channel 10-bit ADC with 2.5 µs conversion time and temperature sensor, a 5-V analog comparator with edge-selectable interrupt and bandgap reference option, and dual 2-channel TPM modules supporting input capture, output compare, and edge- or center-aligned PWM - all functional in stop3 mode alongside the real-time counter driven by a 1 kHz on-chip oscillator.

FAQ
What is the maximum operating temperature supported by the S9S08SG8E2WTGR?
The S9S08SG8E2WTGR is qualified for continuous operation from –40°C to +150°C ambient temperature when packaged in the 16-TSSOP variant. This high-temperature rating is validated per Freescale/NXP specification Rev. 8 (January 2014) and applies specifically to devices ordered with the 'E2' temperature grade suffix. The S9S08SG8E2WTGR maintains full functionality-including ADC, ACMP, and RTC-in this range, with clock accuracy de-rated to ±3% above 125°C.
Does the S9S08SG8E2WTGR support LIN communication natively?
Yes, the S9S08SG8E2WTGR's SCI module includes hardware-level LIN support: it can generate extended-break fields as a LIN master and detect them as a LIN slave. This eliminates software bit-banging overhead and ensures protocol compliance per LIN 2.x specifications. The S9S08SG8E2WTGR requires only an external LIN transceiver (e.g., TJA1020) to complete the physical layer - no additional MCU resources are consumed for frame timing or checksum calculation.
Can the S9S08SG8E2WTGR operate its ADC and analog comparator in low-power stop modes?
Yes, the S9S08SG8E2WTGR supports full ADC and ACMP operation in stop3 mode - the deepest low-power state where the CPU, most clocks, and I/O pads are disabled while selected peripherals remain active. Both modules retain their configuration registers and can trigger interrupts upon completion or threshold crossing. This capability is explicitly documented in the MC9S08SG8 Data Sheet Rev. 8, Section 3.6.3 and Chapter 9/8, enabling wake-on-analog-event designs with sub-microamp quiescent current.
What debug interface does the S9S08SG8E2WTGR use, and what tools support it?
The S9S08SG8E2WTGR uses a single-wire background debug mode (BDM) interface compliant with Freescale's BDM specification. It is supported by the NXP S08 Tower System (TWR-S08SG8), PE Micro Cyclone Pro, and Segger J-Link with BDM firmware. The interface provides full read/write memory access, register inspection, and one hardware breakpoint during in-circuit debugging - sufficient for development and validation of safety-critical firmware without requiring expensive multi-pin JTAG probes.
Is the S9S08SG8E2WTGR pin-compatible with other members of the SG8 family?
Yes, the S9S08SG8E2WTGR is pin-compatible with all 16-TSSOP variants in the MC9S08SGx family, including S9S08SG4E2WTGR and S9S08SG16E2WTGR. They share identical pin assignments, electrical characteristics, and peripheral mapping - differing only in flash/RAM capacity and part marking. This allows hardware reuse across product tiers; firmware must be recompiled for memory layout but requires no PCB redesign when upgrading or downgrading within the SGx 16-TSSOP series.
