3.1 OVERVIEW
Eight 32-pin JEDEC memory sockets on the AR-B7041 can be populated with up to 8MB of EPROM, 4MB of
FLASH, 4MB of SRAM or combinations the EPROM/SRAM or FLASH/SRAM. Each socket accepts the following
memory chips:
EPROM: 27C080 (1Mx8), 27C040 (512Kx8), 27C020
(256Kx8) and 27C010 (128Kx8)
Small Page 5V FLASH: 29C040A (512Kx8), 29C040 (512Kx8),
29C020 (256Kx8), 29C010 (128Kx8),
29C512 (64Kx8), 28EE010 (128Kx8),
28EE011 (128Kx8), 29EE010 (128Kx8),
29EE011 (128Kx8) and 28SF040 (512Kx8)
Large Page 5V FLASH: 29F040 (512Kx8), 29F020 (256Kx8),
29F010 (128Kx8) and 29F512 (64Kx8)
SRAM: 584000 (512Kx8), 581000(128Kx8)
The AR-B7041 uses a 3.6volt Lithium non-chargeable battery to backup stored data in the SRAM memory when
the power is off. Please use low power SRAM chips for a longer data retention period. (These SRAM chips are
usually designated with a <L> in the chip model code.)
