NXP Semiconductors S9S08SG4E2VTJR

Overview

S9S08SG4E2VTJR from NXP Semiconductors (formerly Freescale) is an 8-bit HCS08 microcontroller with 4 KB flash, 256 B RAM, and integrated ADC, ACMP, SCI, SPI, I²C, TPM, and RTC peripherals. It operates at up to 40 MHz CPU frequency, supports stop3 low-power mode, and delivers 10-bit analog conversion in <2.5 µs - deployed in automotive body control modules and industrial sensor nodes.

For engineers reviewing the S9S08SG4E2VTJR datasheet, S9S08SG4E2VTJR pinout, S9S08SG4E2VTJR application, or S9S08SG4E2VTJR equivalent, key selection criteria include its 16-pin TSSOP package, -40°C to 125°C operating range, single-wire BDM debug interface, and support for LIN-compliant SCI with extended break generation.

Technical Context

The S9S08SG4E2VTJR implements the HCS08 CPU core with HC08 instruction set plus BGND, supporting up to 32 interrupt/reset sources. Its internal clock source (ICS) uses a frequency-locked loop (FLL) with precision-trimmed internal reference (±1.5% deviation over –40°C to 125°C), enabling bus frequencies from 2 MHz to 20 MHz.

Peripherals include a 12-channel 10-bit ADC with temperature sensor and internal bandgap reference, a 5-V analog comparator with edge-selectable interrupt and TPM routing capability, and dual 2-channel TPM modules supporting input capture, output compare, and edge- or center-aligned PWM - all functional in stop3 mode.

FAQ

What is the maximum operating frequency of the S9S08SG4E2VTJR CPU core?

The S9S08SG4E2VTJR CPU core operates at up to 40 MHz at temperatures ≤125°C. At higher ambient temperatures (125°C to 150°C), the maximum supported frequency is reduced to 36 MHz to ensure silicon reliability - a specification validated in the official Freescale MC9S08SG8/SG4 datasheet Rev. 8. This thermal derating is enforced by the internal clock source (ICS) module.

Does the S9S08SG4E2VTJR support LIN bus communication?

Yes, the S9S08SG4E2VTJR supports LIN 2.x communication through its SCI module, which includes dedicated hardware for LIN master extended break generation and LIN slave extended break detection. This capability is explicitly documented in the "Peripherals" section of the MC9S08SG8/SG4 datasheet and enables direct integration into automotive body networks without external LIN transceivers.

Can the S9S08SG4E2VTJR operate in ultra-low-power modes with peripherals active?

Yes, the S9S08SG4E2VTJR supports stop3 mode - a very low-power state where the ADC, ACMP, RTC, and SCI remain fully operational and capable of waking the MCU. In this mode, typical current consumption is less than 1 µA, and wake-up latency is sub-microsecond. This behavior is confirmed in Chapter 3 ("Modes of Operation") and Section 9.4.7 ("MCU Stop3 Mode Operation") of the datasheet.

What debug interface does the S9S08SG4E2VTJR provide?

The S9S08SG4E2VTJR features a single-wire background debug mode (BDM) interface compliant with Freescale's BDM specification. It supports in-circuit debugging with one hardware breakpoint, on-chip ICE with eight-deep FIFO, and tag/force breakpoint capabilities - all accessible via the RESET/BKGD pin. No external debugger hardware beyond a standard BDM pod is required.

Is the S9S08SG4E2VTJR pin-compatible with other HCS08 SG-series MCUs?

Yes, the S9S08SG4E2VTJR in 16-TSSOP is pin-compatible with the MC9S08SG8CDT and MC9S08SG16CDT in the same package variant. All share identical pin assignments, electrical characteristics, and peripheral mapping - enabling drop-in replacement for memory-scaling upgrades. This compatibility is verified in the "Device Pin Assignment" chapter (Section 2.1) of the MC9S08SG8/SG4 datasheet Rev. 8.
