Overview

S12 Overview

Freescale S12 and S12X MCUs provide high-performance 16-bit control for automotive and industrial applications. The S12X MCUs feature the innovative XGATE module, designed specifically to handle interrupt events without CPU intervention. As a result, the S12X controller has the high-performance capabilities you would normally expect of a 32-bit controller.

The 68HC12 has 2 8-bit accumulators A and B (referred to as a single 16-bit accumulator, D, when A & B are cascaded so as to allow for operations involving 16 bits), 2 16-bit registers X and Y, a 16-bit program counter, a 16-bit stack pointer and an 8 bit Condition Code Register. The family was extended with the introduction of the MC9S12 derivatives which have bus speeds of up to 25 MHz and flash sizes up to 512 kB. The MC9S12NE64CPVE.MC9S12NE64CPVE. was introduced by Freescale to be the "industry's first single-chip fast-Ethernet Flash microcontroller." It features a 25 MHz HCS12 CPU, 64 kB of FLASH EEPROM, 8 kB of RAM, and an Ethernet 10/100 Mbit/s controller.

S12x Overview

The MC9S12XDP512MALMC9S12XDP512MAL which was introduced in 2004 has a bus speed of 40 MHz and a peripheral co-processor known as the XGATE which allows for some tasks to be offloaded from the CPU. The CPU of the S12X derivative also features several new instructions to increase performance.

Freescale announced the MC9S12XEP100 in May 2006 to further extend the S12X family to 50MHz bus speed and add a Memory protection unit (based on segmentation) and a hardware scheme to provide Emulated EEPROM. HCS12 products contain a single processor, the HCS12X feature the additional XGATE peripheral processor.

The XGATE co-processor is a 16-bit RISC processor operating at twice the main bus clock. It offloads work from the HC12 core by handling interrupts only and does not run a background loop. The first versions of the XGATE do not allow for higher priority interrupts to pre-empt a currently handled interrupt, but the "XGATEV3" as featured in the 9S12XEP100 does allow this. The HC12 can trigger software interrupts on the XGATE core. A semaphore system is implemented to allow the S12X and XGATE cores to share peripherals.

S12 MagniV Mixed-Signal MCUs

The S12 MagniV portfolio helps simplify system design with easy-to-use, expertly integrated mixed-signal microcontrollers for automotive applications. Offering both single-die and dual-die solutions, the S12 MagniV devices are built on proven S12 technology, enabling software and tool compatibility across the entire portfolio. With the right blend of digital programmability and high-precision analog, plus a portfolio of scalable memory options and featuring new monolithic devices based on the revolutionary LL18UHV technology, the S12 MagniV portfolio streamlines automotive design.
