S9S08SG16E1CTJR

The S9S08SG16E1CTJR is an NXP Freescale 8‑bit microcontroller from the S9S08SG16 family. It uses an S08‑core CPU and targets low‑cost, small‑footprint embedded applications. Key features include:
- 16 KB of on‑chip flash for program code
- On‑chip RAM (a few hundred bytes to a couple kilobytes, depending on config)
- Peripherals: timers, ADC, PWM, and common serial interfaces (SCI/UART, SPI, I2C)
- In‑system programming and debugging support (BDM)
- Low‑power modes and a range of package/temperature options
The suffixes indicate packaging and temperature grades: E1 typically denotes an extended temperature range, while CTJR encodes the package type and shipping options. Typical uses are simple control tasks, sensor interfacing, motor control, and other applications where an 8‑bit MCU with modest flash and peripherals is sufficient.

Equivalent product: MC9S08SG16 (NXP/Freescale). The S9S08SG16E1CTJR is part of the SG16 16-KB flash HCS08 family; other SG16 devices with the same silicon and 16 KB flash (different package variants) are cross references. For exact matches, use NXP’s cross-reference tool or distributor catalogs.
