Program memory is 16 KB of on-chip FLASH, organized as 16K x 8 bits. This is sufficient for a moderate-sized firmware image with a small RTOS or a bare-metal scheduler, plus a bootloader if the application needs field updates. The FLASH endurance is rated for the standard 100,000 write/erase cycles typical of this process node, which is adequate for most embedded control applications. The 1 KB (1K x 8) on-chip RAM is the tightest resource. Budget the stack, the HAL's global data, and the application heap against this 1024-byte ceiling. For a typical sensor-node firmware with a 128-byte stack and 256 bytes of global data, about 640 bytes remain for the application heap — enough for a few small buffers but not for large frame buffers or extensive DMA descriptors. ## Wide supply range and industrial temperature grade The internal oscillator is trimmed at the factory and maintains accuracy across this range without an external crystal. ## On-chip peripherals reduce external BOM Integrated peripherals include LVD (low-voltage detect), POR (power-on reset), a PWM module, and a watchdog timer. The LVD and POR together ensure the MCU resets cleanly on power-up and brown-out events without an external supervisor IC. The PWM module can drive a small DC motor or LED dimmer directly, though the I/O pin drive current is typically 5 mA per pin. The 16-channel, 10-bit ADC covers most analog sensor interfaces — temperature, pressure, potentiometer feedback — without an external ADC. The 10-bit resolution gives 1024 steps over the reference voltage; at a 5 V reference, that is about 4.88 mV per step, which is adequate for many industrial sensor outputs. Serial connectivity includes I²C, LINbus, SCI (UART), and SPI. This covers the common buses for sensor modules (I²C for temperature/humidity sensors, SPI for displays or external ADC), actuator communication (LIN for automotive sub-bus), and diagnostic links (SCI for RS-232 or RS-485 via an external transceiver). 23 general-purpose I/O pins in a 28-pin package is a high pin-to-package ratio. Most pins serve dual functions — a single pin may be a GPIO, an ADC input, and a serial interface pin. The pin mux must be configured carefully during firmware initialization to avoid conflicts. ## Active production, ROHS3 compliant The MSL (moisture sensitivity level) is typically MSL-1 for this package, but the actual level should be confirmed from the package marking. The footprint requires a 4-layer board for optimal decoupling and ground plane, though a 2-layer board is possible if the trace routing is carefully managed.","metaTitle":"NXP MC9S08SH16CTL S08 8-bit MCU, 40MHz, 16KB Flash, 28-TSSOP","metaDescription":"NXP MC9S08SH16CTL 8-bit MCU in the S08 series: 40MHz core, 16KB Flash, 1KB RAM, 23 I/O, 16-ch 10-bit ADC, I²C/SPI/LIN, -40 to +85°C.
