PRELIMINARY
FEATURES
32-bit ARM Cortex-M3TM Core
・ Processor version: r2p0 ・ Up to 80MHz Frequency Operation ・ Memory Protection Unit (MPU): improve the reliability of an embedded system ・ Integrated Nested Vectored Interrupt Controller (NVIC): 1 NMI (non-maskable interrupt) and 48
peripheral interrupts and 16 priority levels ・ 24-bit System timer (Sys Tick): System timer for OS task management
On-chip Memories
[Flash memory] ・ Up to 512 Kbyte ・ Read cycle: 0wait-cycle@up to 60MHz, 2wait-cycle(*) above *: Instruction pre-fetch buffer is included. So when CPU access continuously, it becomes 0wait-cycle ・ Security function for code protection
[SRAM] MB9B400 Series contain a total of up to 64Kbyte on-chip SRAM memories. This is composed of two independent SRAM for CPU and DMA C...
