It runs at 40 MHz and carries 16 KB of Flash program memory with 1K x 8 of RAM — a configuration sized for embedded control loops, sensor readout, and simple communication bridges rather than data-heavy applications. The 20-TSSOP package keeps board area small, and the wide supply range (2.7 V to 5.5 V) lets it sit on a regulated 3.3 V rail or a direct 5 V logic bus without a separate level shifter for the MCU itself. On-chip peripherals include a 12-channel 10-bit ADC, PWM, watchdog timer, and low-voltage detect (LVD) with power-on reset (POR). Connectivity covers I²C, SCI (UART), SPI, and LINbus — enough for a LIN slave node in an automotive body module or a sensor hub in an industrial sensor pod. The operating temperature range is -40°C to 85°C, which qualifies it for factory-floor enclosures, outdoor telecom cabinets, and under-hood automotive auxiliary modules where the ambient stays below the 85°C ceiling. ## Supply and temperature — what the ratings mean for the BOM The 2.7 V to 5.5 V supply range means this MCU can run directly from a 3.6 V Li-ion cell or a 5 V industrial rail without an external regulator, saving a BOM line. At the low end, 2.7 V is above the typical brownout threshold of a 3.3 V system, so a 3.3 V rail with 5% tolerance (3.135 V min) still holds margin. The -40°C to 85°C industrial temperature grade covers most factory automation, outdoor telecom, and automotive cabin-zone applications. If the end system sees sustained junction temperatures above 85°C, this part is not the fit — the 85°C ceiling is the absolute operating limit, not a derating target. ## Lifecycle — active, no LTB risk The MC9S08SH16CTJ carries an Active lifecycle status from NXP. The part is ROHS3 compliant, which covers the current EU exemption regime for lead-free assembly.","metaTitle":"NXP MC9S08SH16CTJ 8-bit MCU, 40 MHz, 16 KB Flash, 20-TSSOP","metaDescription":"NXP MC9S08SH16CTJ S08 8-bit MCU: 40 MHz core, 16 KB Flash, 1K x 8 RAM, 12-ch 10-bit ADC, I²C/SCI/SPI/LINbus.

The MC9S08SH16CTJ is in a 20-TSSOP package rated for -40°C to 85°C. The MC9S08SH16CJ is in a 20-SOIC package with a -40°C to 85°C range as well. The TSSOP is narrower (4.4 mm body vs 7.5 mm for SOIC), which affects board footprint and thermal dissipation. Functionally they share the same core, memory, and peripheral set."},{"question":"Can MC9S08SH16CTJ be used as a replacement for MC9S08SH16CJ?","answer":"Yes, it can serve as a functional replacement if the board layout accepts the 20-TSSOP footprint. The MC9S08SH16CJ uses a 20-SOIC package (wider body), so the PCB must accommodate the TSSOP land pattern. Electrically the two parts are identical: same 40 MHz core, 16 KB Flash, 1K x 8 RAM, 12-channel ADC, and peripheral set."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/nxp/MC9S08SH16CTJ","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/nxp/MC9S08SH16CTJ when reusing this data.
