- Vic Gerhardi
General Description
The Am29F080 is an 8 MBit, 5.0 volt-only memory organised as 1,048,576 bytes.
The 8 bits of data appear on DQ0-DQ7.
The Am29F080 is offered in 40 pin TSOP and 44-pin SO packages.
This device designed to be programmed in-system with the standard 5.0 volt Vcc supply.
A 12.0 volt Vpp is not required to program or erase operations.
This device can also be programmed in standard EPROM programmers.
Do not connect the EPROM Programmer to the Host computer yet.
Set the switch settings for the 512K DIL Flash chip.
These are the same for both the 1M and 512K devices.
- Plug in the Z88 Card into the Z88 Extender card
- Unplug and secure the A19 lead from the Header connector on the EPROM Programmer. This is NOT USED for 512K Flash cards.
- Connect the shorting connector to pull up A19.
- Plug in the Z88 Extender card into the programmer's ZIF socket.Â
The Z88 Memory card is used just to get the correct spacing of the two cards but is removed before power is applied to the programmer.
- Remove the Z88 Card
- Connect the power and parallel cable to the EPROM programmerÂ
- Connect to the PC and
- Initialise the EPROM Programmer
Select the chip you wish to use. In this example we are using the Am29F040 512K Flash DIL chip.
