Product data sheet
7.1 ARM Cortex-M0 processor
7.2 On-chip flash program memory
7.3 On-chip SRAM
7.4 Memory map
The ARM Cortex-M0 is a general purpose, 32-bit microprocessor, which offers high
performance and very low power consumption.
The EM773 contains 32 kB of on-chip flash memory.
The EM773 contains a total of 8 kB on-chip static RAM memory.
The EM773 incorporates several distinct memory regions, shown in the following figure.

The AHB peripheral area is 2 megabyte in size, and is divided to allow for up to 128
peripherals. The APB peripheral area is 512 kB in size and is divided to allow for up to 32
peripherals. Each peripheral of either type is allocated 16 kilobytes of space. This allows
simplifying the address decoding for each peripheral.
