The device inte- grates 8K-bytes of 5V byte-alterable nonvolatile memory, 2 bidirectional 8-bit ports, 16 general purpose registers, programmable internal address decoding and a multi- plexed address and data bus. The 5V byte-alterable nonvolatile memory can be used as program storage, data storage, or a combination of both. The memory array is separated into two 4K-byte sections which allows read accesses to one section while a write operation is taking place in the other section. The nonvolatile memory also features Software Data Protection to protect the contents during power transitions, and an advanced Block Protect register which allows individual blocks of the memory to be configured as read-only or read/write. 2899 ILL F01 RESET A12 WC SEL STRA A15 NC A14 A13 PA7 PA6 PA5 PA4 PA3 PA2 PA1 PA0 NC A/D0 A/D1 A/D2 A/D3 A/D4 VSS 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 48 47 46 45 44 43 42 41 40 39 38 37 36 35 34 33 32 31 30 29 28 27 26 25 VCC R/W AS A8 A9 A11 NC IRQ STRB PB7 PB6 PB5 PB4 PB3 PB2 PB1 PB0 NC E A10 CE A/D7 A/D6 A/D5 X68C75 DIP SLIC Concurrent Read During Write, Block Lock, and SLIC® E2 are registered trademarks of Xicor, Inc.
