Description:
• Max. Clock 10 MHz
The Microchip Technology Inc. 25AA080C/D,
25LC080C/D (25XX080C/D*) are 8 Kbit Serial Electri-
cally Erasable PROMs. The memory is accessed via a
simple Serial Peripheral Interface (SPI) compatible
serial bus. The bus signals required are a clock input
(SCK) plus separate data in (SI) and data out (SO)
lines. Access to the device is controlled through a Chip
Select (CS) input.
• Low-Power CMOS Technology:
- Max. write current: 5 mA at 5.5V
- Read current: 5 mA at 5.5V, 10 MHz
- Standby current: 5 A at 5.5V
• 1024 x 8-bit Organization
• 16 Byte Page (‘C’ version devices)
• 32 Byte Page (‘D’ version devices)
• Self-Timed Erase and Write Cycles (5 ms max.)
• Block Write Protection:
Communication to the device can be paused via the
hold pin (HOLD). While the device is paused, transi-
tions on its inputs will be ignored, with the exception of
Chip Select, allowing the host to service higher priority
interrupts.
- Protect none, 1/4, 1/2 or all of array
• Built-In Write Protection:
The 25XX080C/D is available in standard packages
including 8-lead PDIP and SOIC, and advanced pack-
aging including 8-lead MSOP, TSSOP, and 2x3 TDFN.
All packages are Pb-free and RoHS compliant.
- Power-on/off data protection circuitry
- Write enable latch
- Write-protect pin
• Sequential Read
• High Reliability:
Package Types (not to scale)
- Endurance: > 1M erase/write cycles
- Data retention: > 200 years
- ESD protection: > 4000V
