M27V512 M27V512 512 Kbit (64Kb x 8) Low Voltage UV EPROM and OTP EPROM DATA BRIEFING LOW VOLTAGE READ OPERATION: 3V to 3.6V FAST ACCESS TIME: 100ns LOW POWER CONSUMPTION: Active Current 10mA at 5MHz Standby Current 10µA PROGRAMMING VOLTAGE: 12.75V ± 0.25V PROGRAMMING TIME: 100µs/byte (typical) ELECTRONIC SIGNATURE Manufacturer Code: 20h Device Code: 3Dh DESCRIPTION The M27V512 M27V512 is a low voltage 512 Kbit EPROM offered in the two ranges UV (ultra viloet erase) and OTP (one time programmable). It is ideally suited for microprocessor systems and is organized as 65,536 by 8 bits. The M27V512 M27V512 operates in the read mode with a supply voltage as low as 3V. The decrease in operating power allows either a reduction of the size of the battery or an increase in the time between battery recharges. The FDIP28W FDIP28W (window ceramic frit-seal package) has transparent lid which allows the user to expose the chip to ultraviolet light to erase the bit pattern. A new pattern can then be written to the device by following the programming procedure. For applications where the content is programmed only one time and erasure is not required, the M27V512 M27V512 is offered in PDIP28 PDIP28, PLCC32 PLCC32 and TSOP28 TSOP28 (8 x 13.4 mm) packages. 28 28 1 1 FDIP28W FDIP28W (F) PDIP28 PDIP28 (B) PLCC32 PLCC32 (K) TSOP28 TSOP28 (N) 8 x 13.4mm Logic Diagram VCC 16 8 A0-A15 A0-A15 E Q0-Q7 M27V512 M27V512 GVPP VSS AI00732B AI00732B B27V512/805 B27V512/805 Complete data available on DATA-on-DISC CD-ROM or at www.st.com 1/3 M27V512 M27V512 DIP Pin Connections A15 A12 A7 A6 A5 A4 A3 A2 A1 A0 Q0 Q1 Q2 VSS TSOP Pin Connections 28 1 27 2 26 3 25 4 24 5 23 6 22 7 M27V512 M27V512 21 8 20 9 19 10 18 11 17 12 13 16 14 15 VCC A14 A13 A8 A9 A11 GVPP A10 E Q7 Q6 Q5 Q4 Q3 GVPP A11 A9 A8 A13 A14 VCC A15 A12 A7 A6 A5 A4 A3 22 28 1 21 M27V512 M27V512 7 15 14 8 AI01907 AI01907 A10 E Q7 Q6 Q5 Q4 Q3 VSS Q2 Q1 Q0 A0 A1 A2 AI00734B AI00734B LCC Pin Connections Signal Names M27V512 M27V512 9 25 A8 A9 A11 NC GVPP A10 E Q7 Q6 VSS DU Q3 Q4 Q5 Q1 Q2 17 AI00733B AI00733B Warning: NC = Not Connected, DU = Don't Use 2/3 Data Outputs E 1 32 A6 A5 A4 A3 A2 A1 A0 NC Q0 Address Inputs Q0-Q7 A7 A12 A15 DU VCC A14 A13 A0-A15 A0-A15 Chip Enable GVPP Output Enable / Program Supply VCC Supply Voltage VSS Ground M27V512 M27V512 ORDERING INFORMATION SCHEME Example: M27V512 M27V512 Speed -100 (1) -100 Package K 1 TR Temperature Range FDIP28W FDIP28W 1 0 to 70 °C B PDIP28 PDIP28 6 40 to 85 °C K PLCC32 PLCC32 N Option TSOP28 TSOP28 8 x 13.4mm 100 ns F -120 120 ns -150 150 ns -200 200 ns TR Tape & Reel Packing Note: 1.
