MC9S12A256CPVE Description
Freescale Semiconductor’s MC9S12A256 Flash microcontroller (MCU) is the next generation of the highly successful 68HC12 architecture. Using Freescale’s industry-leading 0.25 μs Flash, the A256 is part of a pin-compatible family that scales from 32 KB to 512 KB of Flash memory. The
MC9S12A256 provides an upward migration path from Freescale’s 68HC08, 68HC11 and 68HC12 architectures for applications that need larger memory, more peripherals and higher performance.
