Description

These 32-bit automotive microcontrollers are a family of system-on-chip (SoC) devices that contain all the features of the

MPC5500 family and many new features coupled with high performance 90 nm CMOS technology to provide substantial

reduction of cost per feature and significant performance improvement. The advanced and cost-efficient host processor core of

this automotive controller family is built on Power Architecture® technology. This family contains enhancements that improve

the architecture’s fit in embedded applications, includes additional instruction support for digital signal processing (DSP),

integrates technologies—such as an enhanced time processor unit, enhanced queued analog-to-digital converter, Controller

Area Network, and an enhanced modular input-output system—that are important for today’s lower-end powertrain

applications. This device family is a completely compatible extension to Freescale’s MPC5500 family. The device has a single

level of memory hierarchy consisting of up to 94 KB on-chip SRAM and up to 1.5 MB of internal flash memory. The device

also has an external bus interface (EBI) for ‘calibration’. This external bus interface has been designed to support most of the

standard memories used with the MPC5xx and MPC55xx families.
