AT89STK-03 Hardware User Guide
EEPROM Settings
2 x 48 headers
This MCU demonstration board supports different versions of the AT8XC5122 and
AT83C23 microcontrollers:
- Flash versions
- CRAM versions
- ROM versions
and different versions of embedded bootloaders (DPW, DRV, DSU).
PLCC68 package is only available in CRAM version but it possible to have it function in
flash mode by adding an external 256Kb (32KB x 8) E2PROM on the 8 pin DIP socket. It
is possible to write protect the E2PROM by adding a jumper on the WP location.
The demonstration board is configured to work with parts implementing the latest ver-
sion of the bootloader (DSU or upper versions). If parts implementing older versions are
used, headers must be added on A0 ,A1, P36, P37, P42, P43 locations and the configu-
ration of the board must changed accordingly.
Table 2-2. E2PROM settings
Refer to bootloader datasheets for further information.
These headers support the optional C51 generic board.
