Description:
Features:
The Microchip Technology Inc. 25AA160C/D,
25LC160C/D (25XX160C/D*) are 16 Kbit Serial
Electrically Erasable PROMs. The memory is accessed
• Max. Clock 10 MHz
• Low-Power CMOS Technology:
- Max. write current: 5 mA at 5.5V
- Read current: 5 mA at 5.5V, 10 MHz
- Standby current: 5 uA at 5.5V
• 2048 x 8-bit Organization
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.
• 16-Byte Page (‘C’ version devices)
• 32-Byte Page (‘D’ version devices)
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.
• Self-Timed Erase and Write Cycles (5 ms max.)
• Block Write Protection:
- Protect none, 1/4, 1/2 or all of array
• Built-In Write Protection:
The 25XX160C/D is available in standard packages
including 8-lead PDIP and SOIC, and advanced
packaging 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
Package Types (not to scale)
• High Reliability:
- Endurance: > 1M erase/write cycles
- Data retention: > 200 years
- ESD protection: > 4000V
• Temperature Ranges Supported:
