Freescale S08SG16 and S08SG32 8-Bit Microcontrollers

Freescale Semiconductor’s S08SG16 and S08SG32 8-bit microcontrollers (MCU) provide a flexible, general-purpose solution for body control modules, LIN(tm) nodes, mirror modules, window-lift, battery management systems, HVAC control, and heated seat modules. Samples of the S08SG16/32 devices are available now.

Operating at up to 40 MHz with 16K and 32K flash memory options, the S08SG16/32 MCUs stretch the boundaries of 8-bit performance. The S08SG16 and S08SG32 MCUs are ideal for motor control applications. The devices also are designed to enable simplified development of LIN systems through an on-chip serial communications interface (SCI). The SCI module allows LIN break detection and synchronization without the use of an external timer channel.

The S08SG16/32 devices’ high level of integration helps reduce development cost, saves board space and enhances system-level quality by eliminating the need for peripheral board components, such as external clock sources. Other notable features include low voltage inhibit (LVI) circuits, voltage regulators, I/O multiplexers, watchdog circuits and analog-to-digital converters (ADCs).

The S08SG16/32 devices offer an on-chip background debug mode (BDM) capability that enables developers to perform non-intrusive debugging and emulation on the fly. The BDM feature is critical for debugging multi-MCU systems in chassis and powertrain applications without interfering with software execution.
