S9S08SG16E1CTJ 개요

The NXP Semiconductors S9S08SG16E1CTJ is an 8-bit microcontroller unit (MCU) based on the S08 CISC core, operating at up to 40 MHz with 16KB (16K x 8) of Flash program memory and 1KB of RAM, housed in a 20-pin TSSOP (4.40 mm width) surface-mount package with automotive qualification for -40C to +85C ambient operation.

An 8-bit MCU is an integrated circuit that combines a processor core, memory, and peripherals on a single chip, sitting within the broader hierarchy of microcontroller -> embedded processor -> semiconductor. Entry-level 8-bit MCUs like the S08SG family are widely used for cost-sensitive control tasks such as LIN slave nodes, sensor interfacing, and simple actuator control, where 32-bit processors would add unnecessary cost and complexity.

Key features of the S9S08SG16E1CTJ include the 40 MHz S08 core, 16KB Flash program memory, 1K x 8 RAM, and 16 general-purpose I/O lines. The oscillator type is internal, which reduces external component count and bill-of-material cost, an important benefit in space-constrained automotive modules.

The S08SG family from NXP (formerly Freescale Semiconductor) is positioned as an entry-level to mid-range offering designed for LIN slave, general market, high-temperature, and space-constrained applications. The automotive qualification of this grade makes it suitable for body electronics and convenience modules that must survive harsh in-vehicle environments, while the 20-pin TSSOP keeps PCB footprint minimal for tightly packed boards.

Typical applications include LIN slave nodes in automotive body electronics, small appliance and general-market motor control, and space-constrained sensor or actuator interface boards. The internal oscillator and rich S08 peripheral set let designers implement these functions with minimal external circuitry.

A key design consideration is lifecycle: NXP lists the S9S08SG16E1CTJ as End of Life, so new designs should verify the NXP-recommended replacement or select an active S08/Kinetis alternative. Existing designs should secure last-time-buy inventory.

This page synthesizes distributor pricing context, drop-in alternatives, and practical design notes not found in the manufacturer datasheet, providing engineering decision support for both new designs and EOL migration.

일반적인 애플리케이션

S9S08SG16E1CTJ 적합 용도: 6 애플리케이션s: Automotive LIN Slave Nodes, Body Electronics Modules, Small Appliance and General Market Control, Space-Constrained Sensor Interfaces, Motor Starters and Actuator Control, EOL Migration and Legacy System Maintenance.

🚗

Automotive LIN Slave Nodes

The S9S08SG16E1CTJ is explicitly designed by NXP for LIN slave applications, combining the 40 MHz S08 core with 16KB Flash and an internal oscillator that eliminates the external crystal required by many competing MCUs. In a typical LIN node such as a window lift, seat adjuster, or wiper module, the MCU handles LIN 2.x frame scheduling, diagnostic services, and PWM actuator control while sleeping at low current between frames. The automotive qualification and -40C to +85C rating ensure reliability in cabin and under-dash environments. The 20-pin TSSOP footprint keeps node PCB area small, and the internal oscillator reduces bill-of-material cost - a key factor in high-volume automotive programs.

🚗

Body Electronics Modules

Automotive body control functions - mirror switches, lighting logic, and convenience closures - need a low-cost, qualified MCU with adequate I/O and Flash. The S9S08SG16E1CTJ offers 16 general-purpose I/O lines and 16KB Flash, sufficient for switch debouncing, relay or LED driver sequencing, and fault diagnostics. Its 3.3 V/5 V operation matches the mixed-voltage rails common in vehicle electrical architectures, and the 20-pin TSSOP package fits into the compact connector-adjacent PCB regions typical of body modules. Because the part is EOL, designers maintaining these modules should pair the SG16 with last-time-buy inventory, while new body-electronics designs should select an active NXP S08 successor to secure long-term supply.

💡

Small Appliance and General Market Control

Beyond automotive, the S08SG family targets the general market, making the S9S08SG16E1CTJ suitable for small appliance control boards: fan speed sequencing, temperature-based heater control, and user-interface scanning. The internal oscillator removes the crystal from the BOM, and the 16 I/O lines cover buttons, LEDs, and a TRIAC or relay drive with margin. At 40 MHz, the S08 core executes control loops and ADC-filtering tasks comfortably within the timing budgets of appliance firmware. The 5 V operation simplifies interfacing with mains-derived supplies that lack regulated 3.3 V rails. Although this grade is automotive-qualified, its general-market pedigree keeps it cost-effective for consumer and white-goods applications.

🧩

Space-Constrained Sensor Interfaces

With a 20-pin TSSOP body only 4.40 mm wide, the S9S08SG16E1CTJ fits dense sensor-interface boards where a 32- or 44-pin package cannot. Typical roles include conditioning outputs from pressure, position, or temperature sensors and digitizing them before passing data over LIN or UART to a domain controller. The 16KB Flash stores calibration tables and linearization code, while the 1KB RAM buffers sampling data. The internal oscillator supports standalone operation at the sensor node. Designers should budget the limited 16 I/O pins carefully, since several pins are shared with communication and debug functions; the datasheet pin muxing table governs allocation in dense layouts.

⚙️

Motor Starters and Actuator Control

Small brushed-DC motors in HVAC dampers, locks, and pumps require simple PWM drive and current-limit supervision rather than complex field-oriented control. The S9S08SG16E1CTJ's 40 MHz core generates PWM with software timers, monitors overcurrent via comparator inputs, and implements stall detection in firmware. The 5 V operation directly drives logic-level MOSFET gate drivers, and the -40C to +85C range suits engine-bay-adjacent actuator locations. The internal oscillator's accuracy is adequate for PWM frequencies used in actuator control, though closed-loop speed regulation from back-EMF should validate timing tolerance. For higher-performance motor control, NXP's DZ-family devices with dedicated PWM modules are the natural upgrade path.

🔧

EOL Migration and Legacy System Maintenance

A primary real-world use of the S9S08SG16E1CTJ today is sustaining production of legacy automotive and industrial boards after NXP's End-of-Life announcement. Procurement teams must bridge supply with open-market purchases from sources such as Win Source or Avaq while engineering qualifies a migration path. The nearest like-for-like migration targets are other SG16 ordering variants (same die, same TSSOP-20 footprint) or the active MC9S08SL16CTJ, which shares core size and memory class. A sound migration plan verifies pinout identity, revalidates oscillator accuracy and peripheral timing, and runs the existing firmware regression suite before releasing the redesign to production.

What is the S9S08SG16E1CTJ microcontroller?
The S9S08SG16E1CTJ is an NXP Semiconductors 8-bit microcontroller based on the S08 CISC core. According to NXP and DigiKey product data, it runs at 40 MHz, integrates 16KB (16K x 8) of Flash and 1KB of RAM, provides 16 I/O lines, and comes in a 20-pin TSSOP package with automotive qualification for -40C to +85C operation.
Is the S9S08SG16E1CTJ still in production?
No. The NXP official product page lists the S9S08SG16E1CTJ as End of Life, including discontinuance and replacement documentation. Existing designs should execute a last-time-buy through distributors or open-market sources, while new designs should adopt the NXP-recommended replacement or an active S08-family device such as the MC9S08SL16 or PT16 series.
What is the operating temperature range of S9S08SG16E1CTJ?
The S9S08SG16E1CTJ operates from -40C to +85C ambient. This automotive-qualified range, as stated in NXP product listings, covers under-hood-adjacent and body-electronics environments where consumer-grade 0C to +70C parts would not be reliable. Note that some S08SG family members extend up to 150C ambient, but this specific CTJ grade is specified to +85C.
How much Flash and RAM does the S9S08SG16E1CTJ have?
The S9S08SG16E1CTJ contains 16KB (16K x 8) of Flash program memory and 1KB (1K x 8) of RAM. According to DigiKey's product listing, this memory combination supports typical LIN slave applications, small state machines, and sensor-processing firmware while keeping the die small and the cost low within the S08SG family lineup.
What is the best drop-in replacement for S9S08SG16E1CTJ?
The closest same-family drop-in candidates are other S9S08SG16E1 parts in the 20-pin TSSOP footprint, such as the S9S08SG16E1VTJ and S9S08SG16E1MTJ variants, which share the same S08 core, 16KB Flash, and pinout. Within NXP's broader portfolio, the MC9S08SL16CTJ (also 16KB Flash, 20-pin TSSOP) is a practical replacement candidate. Always verify the pinout and the NXP PCN replacement document before committing.
Where to buy S9S08SG16E1CTJ online?
The S9S08SG16E1CTJ is End of Life, so authorized stock at DigiKey and Mouser is limited or exhausted; the DigiKey listing shows the related CTJR reel variant has shipped historically. Available sources are open-market and independent distributors such as Win Source, Avaq, Censtry, and Nevsemi. Because EOL parts carry counterfeit risk, buy from vetted distributors and request traceability documentation.
What is the price of S9S08SG16E1CTJ?
Unit pricing for the S9S08SG16E1CTJ is not published in the verified data as of 2026-10-18. Because the part is End of Life, pricing is quote-based and varies significantly between open-market distributors and remaining authorized inventory. Contact distributors such as Win Source or Avaq for an RFQ, and budget for EOL premiums compared with original production-era pricing.
What is the difference between S9S08SG16E1CTJ and S9S08SG16E1CTJR?
The two part numbers share the identical die, 16KB Flash, 40 MHz S08 core, and 20-pin TSSOP package; the R suffix denotes Tape and Reel packaging instead of Tube. Electrically and functionally they are the same device, so the CTJR can substitute for the CTJ wherever the reel packaging quantity suits production. According to DigiKey, both are listed as S08 microcontroller ICs with the same specifications.
S9S08SG16E1CTJ vs MC9S08SL16CTJ - which is better?
For a new design, the MC9S08SL16CTJ is better because it remains active while the S9S08SG16E1CTJ is End of Life. Both are NXP 8-bit S08-family MCUs with 16KB Flash in a 20-pin TSSOP package. The S9S08SG16E1CTJ is preferable only for maintaining existing automotive-qualified designs where the SG-family peripheral set and qualification history matter and redesign risk must be avoided.
Is S9S08SG16E1CTJ suitable for LIN slave applications?
Yes. According to NXP's family description, the S08SG family is designed specifically for LIN slave, general market, high-temperature, and space-constrained applications. The 40 MHz S08 core, 16KB Flash, internal oscillator, and 16 I/O lines provide the resources needed for a LIN slave node handling periodic frame scheduling, diagnostics, and simple actuation without external crystal circuitry.
Is S9S08SG16E1CTJ automotive qualified?
Yes. Multiple verified listings, including DigiKey, Mouser, and digchip datasheet summaries, describe the S9S08SG16E1CTJ as Automotive Qualified with a -40C to +85C operating range. This qualification makes it appropriate for automotive body electronics, convenience modules, and LIN nodes, unlike consumer-grade S08 variants. Always confirm the exact qualification level in the NXP qualification documentation for your program.

The S9S08SG16E1CTJ datasheet is available from the official NXP product page at nxp.com/part/S9S08SG16E1CTJ, which includes the data sheet section with discontinuance and replacement documentation. The underlying family documentation is the MC9S08SG32 datasheet set, which covers SG16 derivatives. Third-party mirrors such as digchip.com also host the PDF, but always use the NXP site for the latest revision and errata.
Where can I find the S9S08SG16E1CTJ pinout?
The complete 20-pin TSSOP pinout for the S9S08SG16E1CTJ is provided in the MC9S08SG family datasheet (the SG16 shares the SG32 documentation set) on the NXP product page. Because this page's verified data does not include the pin-by-pin net names, we do not reproduce the pinout here to avoid errors; download the official NXP datasheet for the authoritative pin diagram and pin function table.
What are the key specifications of S9S08SG16E1CTJ that engineers should know?
Engineers should know: 8-bit S08 CISC core at 40 MHz; 16KB (16K x 8) Flash program memory; 1KB (1K x 8) RAM; 16 general-purpose I/O; internal oscillator; 3.3 V or 5 V operation; -40C to +85C automotive-qualified temperature range; 20-pin TSSOP (4.40 mm width) surface-mount package; tube packaging; and End of Life lifecycle status per NXP.
Can the S9S08SG16E1VTJ replace the S9S08SG16E1CTJ?
Yes, in most cases. The S9S08SG16E1VTJ is the same SG16 device family with the same 20-pin TSSOP footprint, S08 core, and 16KB Flash; the letter code difference reflects grading/packaging ordering variants within the family.

선택 가이드

Choose the S9S08SG16E1CTJ only for sustaining existing automotive-qualified designs, and secure last-time-buy inventory since NXP has declared End of Life. If supply is exhausted, first try the same-die variants S9S08SG16E1VTJ or S9S08SG16E1MTJ, which require no PCB or firmware changes. For new designs, select the active MC9S08SL16CTJ for like-for-like 16KB/20-TSSOP continuity, or the MC9S08PT16AVWJ when you want a modern active S08 part with updated peripherals at the cost of a pinout re-check. If your application needs crystal-level clock accuracy for LIN baud tolerance, evaluate whether the internal oscillator of any SG16 variant meets your timing budget or whether a crystal-capable family member is required.

설계 노트

The S9S08SG16E1CTJ is End of Life per the NXP product page. Do not start new designs with this part. For existing designs, execute a last-time-buy sized to cover field-service projections plus attrition, and download NXP's discontinuance and replacement Product Change Notice from the part page to confirm the officially recommended successor before qualifying a substitute.

The device operates from 3.3 V or 5 V supplies. Decouple VDD with a 0.1 uF ceramic capacitor placed within 5 mm of the pin, plus a 1-10 uF bulk capacitor per supply rail. Because the oscillator is internal, supply noise directly affects clock accuracy and ADC results; keep the analog supply node quiet and avoid routing PWM return currents under the MCU.

The 20-pin TSSOP has a 0.65 mm pin pitch; use a standard TSSOP-20 land pattern per the NXP packaging document and verify solder-mask definitions for fine-pitch assembly. Allocate the 16 I/O pins before routing - several pins are multiplexed with debug (BGND/BKGD) and communication functions, so locking the debug access pin early avoids a respin.
