CY91570
32-bit MCU which covers the range from 640KB to 2MB embedded Flash memory
Based on Infineon's proprietary high performance FR81S core, these automotive MCUs offer high computing performance combined with a rich peripheral feature set which make them highly suitable for vehicle instrumentation cluster applications. Maximum 6 channels of Stepper Motor Controller provide cost efficient electro-mechanical cluster design. All members of the CY91570 series are based on Infineon's Flash Memory technology offering program storage as well as a separate Work Flash as E2PROM emulation memory.
A proprietary 32-bit RISC CPU core features an operating speed up to 128 MHz, with 160 DMIPS performance. This high-level RISC core, which is based on a Harvard architecture with separated instruction and data bus, is optimized for applications that require high-speed control. An optimized instruction set assures low-code-size densities and high execution speeds.
The latest generation in the FR81 features an improved CPU core with an enhanced instruction pipeline for reduced branch penalty. The newest members of the family (the CY91520, CY91570, CY91580 and CY91590 MCU-series) also include a single, precision Floating Point Unit (FPU), providing the extra computing power that complex control algorithms require.
Memory densities range from 384 KB to 2 MB Flash. The highly reliable, high-speed Flash memory has an endurance of 100,000 write/erase cycles with up to 20 years of data retention.
Highly optimized for automotive instrument cluster application with high-current stepper motor controller/driver, with segment LCD controller/driver which enables optimized and best performance design in the application category.
The devices include Controller Area Network (CAN), FlexRay and Local Interconnect Network (LIN) interfaces. These interfaces, combined with the large, on-chip memory capacity, enable efficient data collection, processing and distribution. Many devices offer an external bus interface that can e.g. be connected to Infineon's standalone FlexRay controller or to the latest generation of graphics controllers to build full-featured dashboards, driver-information and advanced driver-assistance systems.
Infineon and its external partners offer a full set of development tools such as starter kits, hardware and software debuggers, and third-party-supported automotive operating systems like AUTOSAR and OSEK.
