1 / 12 page 1 Features • Single Voltage Operation – 5V Read – 5V Reprogramming • Fast Read Access Time - 90 ns • Internal Program Control and Timer • 16K bytes Boot Block With Lockout • Fast Erase Cycle Time - 10 seconds • Byte-By-Byte Programming - 10 µs/Byte Typical • Hardware Data Protection • DATA Polling For End Of Program Detection • Low Power Dissipation – 50 mA Active Current – 100 µA CMOS Standby Current • Typical 10,000 Write Cycles Description The AT49F080 is a 5-volt-only in-system Flash Memory device. Its 8-megabits of memory is organized as 1,024,576 words by 8-bits. Manufactured with Atmel’s advanced nonvolatile CMOS technology, the device offers access times to 90 ns with power dissipation of just 275 mW over the commercial temperature range. When the device is deselected, the CMOS standby current is less than 100 µA. The device contains a user-enabled “boot block” protection feature. Two versions of the feature are available: the AT49F080 locates the boot block at lowest order addresses (“bottom boot”); the AT49F080T locates it at highest order addresses (“top boot”). 8-Megabit (1M x 8) 5-volt Only Flash Memory AT49F080 AT49F080T AT49F080/080T 0584B-A–8/97 Pin Configurations Pin Name Function A0 - A19 Addresses CE Chip Enable OE Output Enable WE Write Enable RESET Reset RDY/BUSY Ready/Busy Output I/O0 - I/O7 Data Inputs/Outputs NC No Connect CBGA Top View A B C D E F 1 234567 A5 A4 A6 A3 A2 A1 A8 A7 A9 I/O1 A0 I/O0 A11 A10 RST NC I/O3 I/O2 NC VCC CE VCC GND GND A12 A13 A14 I/O4 I/O6 I/O5 A15 NC A16 I/O7 OE RY/BY A17 A18 A19 NC NC WE (continued) SOIC 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 44 43 42 41 40 39 38 37 36 35 34 33 32 31 30 29 28 27 26 25 24 23 NC RESET A11 A10 A9 A8 A7 A6 A5 A4 NC NC A3 A2 A1 A0 I/O0 I/O1 I/O2 I/O3 GND GND VCC CE A12 A13 A14 A15 A16 A17 A18 A19 NC NC NC NC WE OE RDY/BUSY I/O7 I/O6 I/O5 I/O4 VCC TSOP Top VIew Type 1 A17 A16 A14 A15 A12 CE A13 A10 A8 A9 RESET A11 NC VCC 1 2 4 3 6 5 10 9 7 8 14 13 11 12 I/O2 I/O3 I/O1 I/O0 VCC I/O4 GND GND I/O6 I/O5 RDY/BUSY I/O7 OE WE 33 32 30 31 28 27 29 36 34 35 38 37 39 40 25 26 A1 A0 15 16 A7 A6 A5 20 19 A2 A3 22 21 23 24 17 18 A4 A19 A18 NC NC |
