AT89C5132

5. Address Spaces

The AT8xC5132 derivatives implement four different address spaces:

• Program/Code Memory

• Boot Memory

• Data Memory

• Special Function Registers (SFRs)

5.0.1 Code Memory

The AT89C5132 implements 64K Bytes of on-chip program/code memory in Flas h technology.

The Flash memory increases ROM functionality by enabling in-circuit el ectrical erasure and pro-

gramming. Thanks to the internal charge pump, the high volt age need ed for progr amming or

erasing Flash cells is generated on-chip using the standard VDD voltage. Thus, the AT89C5132

can be programmed using only one voltage and allows in application software programming

commonly known as IAP. Hardware programming mode is also available using specific pro-

gramming tools.

5.0.2 Boot Memory

The AT89C5132 implements 4K Bytes of on-chip boot memory provided in Flash technology.

This boot memory is delivered programmed with a standard bootloader s oftware allowing in sys-

tem programming commonly known as ISP. It also contains some Application Programming

Interfaces routines commonly known as API allowing user to develop his own bootloader.

5.0.3 Data Memory

The AT89C5132 derivatives implement 2304 bytes of on-chip data RAM. T his memory is divided

in two separate areas:

• 256 bytes of on-chip RAM memory (standard C51 memory).

• 2048 bytes of on-chip expanded RAM memory ( ERAM accessible via MOVX instructions).
