The Microchip Technology Inc. 24VL024/24VL025 is a
2 Kbit Serial Electrically Erasable PROM with
operation down to 1.5V. The device is organized as a
single block of 256 x 8-bit memory with a 2-wire serial
interface. Low-current design permits operation with
Note 1: 100 kHz for V CC < 1.8V
Features:
? Single-Supply with Operation down to 1.5V
? Low-Power CMOS Technology:
- 400 μ A active current, maximum
- 1 μ A standby current, maximum
? 2-Wire Serial Interface Bus, I 2 C? Compatible
? Schmitt Trigger Inputs for Noise Suppression
? Output Slope Control to Eliminate Ground Bounce
maximum standby and active currents of only 1 μ A and
400 μ A, respectively. The device has a page write
capability for up to 16 bytes of data. Functional address
lines allow the connection of up to eight 24VL024/
24VL025 devices on the same bus for up to 16 Kbits of
contiguous EEPROM memory. The device is
available in the standard 8-pin PDIP, 8-pin SOIC (150
mil), TSSOP, 2x3 TDFN and MSOP packages. The
24VL025 is also available in the 6-lead, SOT-23
package.
