Atmel ATA5830/ATA5830N

1.3.7

Customer Application Software

All the functionality is implemented in 24KB of ROM firmware and controlled by SPI com-

mands. In addition, 6KB of Flash is available to enable customer specific software

functionality. Examples for flash customization are a) extension of SPI commands, b) usage of

a single wire interface instead of SPI, c) polling adaptations, d) protocol handling, etc. To

achieve customer specific functionality, parts of the ROM code can be replaced with Flash

code.

1.3.8

EEPROM Configuration

The configuration of the device e.g. RF-frequency, modulation type, data rate, etc. is stored in

512KB of EEPROM that is integrated within the Atmel

of the SPI control since most of the configuration comes from the EEPROM. In most applica-

tions, only the received or transmitted data and short SPI commands are required. The device

is delivered with a standard configuration; only deviations from that need to be configured.

Device configuration uses only a part of the 512KB of EEPROM leaving free space available

for additional customer data storage.
