What is the ERC32?

The ERC32 is a three-chip computing core implementing a SPARC V7 processor and associated support circuitry for embedded space applications. The integer and floating-point units (90C601E & 90C602E) are based on the Cypress 7C601 and 7C602, with additional error-detection and recovery functions. The memory controller (MEC) implements system support functions such as address decoding, memory interface, DMA interface, UARTs, timers, interrupt control, write-protection, memory reconfiguration and error-detection and reconfiguration. The core is designed to work at 25MHz, but using space qualified memories will limit the system frequency to around 15 MHz, resulting in a performance of 10 mips and 2 mflops.

A 35 MHz / 25 mips single-chip version of the ERC32 (TSC695E) replaces the three-chip set, and is available as a starter kit from Atmel (Temic Semiconductors).
