1. Description
The AT69170E FPGA configuration memory (configurator) is an electrically erasable
and re-programmable RadHard memory organized as 4Mx1bit. It is an easy-to-use
and cost-effective configuration memory for space Field Programmable Grid Array
(FPGA). It is manufactured with ATMEL 0.18µm low power non volatile CMOS
RadHard process.
It is packaged in a 18-pin 305 Mils wide Flat Pack package. AT69170E uses a simple
serial-access procedure to configure one or more FPGA devices. A two wire interface
(TWI) is available for memory programming.
The user can select the polarity of the reset function by programming a dedicated test
sequence. These devices also support a write-protection mechanism within its pro-
gramming mode.
The factory blanks devices to all ‘1’ before shipping.
