3.1

Functional description

The STR750F family includes devices in 2 package sizes: 64-pin and 100-pin. Both types

have the following common features:

ARM7TDMI-S

core with embedded Flash & RAM

STR750F family has an embedded ARM core and is therefore compatible with all ARM tools

and software. It combines the high performance ARM7TDMI-S

CPU with an extensive

range of peripheral functions and enhanced I/O capabilities. All devices have on-chip high-

speed single voltage FLASH memory and high-speed RAM.

Figure 1

shows the general block diagram of the device family.

Embedded Flash memory

Up to 256 KBytes of embedded Flash is available in Bank 0 for storing programs and data.

An additional Bank 1 provides 16 Kbytes of RWW (Read While Write) memory allowing it to

be erased/programmed on-the-fly. This partitioning feature is ideal for storing application

parameters.

●

When configured in burst mode, access to Flash memory is performed at CPU clock

speed with 0 wait states for sequential accesses and 1 wait state for random access

(maximum 60 MHz).

When not configured in burst mode, access to Flash memory is performed at CPU

clock speed with 0 wait states (maximum 32 MHz)

●

Embedded SRAM

16 Kbytes of embedded SRAM accessed (read/write) at CPU clock speed with 0 wait states.

Enhanced interrupt controller (EIC)

In addition to the standard ARM interrupt controller, the STR750F embeds a nested interrupt

controller able to handle up to 32 vectors and 16 priority levels. This additional hardware

block provides flexible interrupt management features with minimal interrupt latency.
