SST49LF004C-33-4C-NHE Product details

PRODUCT DESCRIPTION

The SST49LF00xC flash memory devices are designed to interface with host controllers (chipsets) that support a low pin-count (LPC) interface for system firmware applications. The SST49LF00xC device complies with Intel’s LPC Interface Specification 1.1, supporting a Burst-Read (up to 128 bytes in a single operation) which enables a 15.6 MByte per second data transfer. The LPC interface operates with 5 signal pins versus 28 pins of a 8-bit parallel flash memory. This frees up pins on the ASIC host controller resulting in lower ASIC costs and a reduction in overall system costs due to simplified signal routing.

   - one 16-KByte Boot Block

   - two 8-KByte Parameter Blocks

   - one 32-Kbyte Parameter Block

   - 15 64-KByte Main Blocks

• Fast Sector-Erase/Program Operation

   – Sector-Erase Time: 18 ms (typical)

   – Block-Erase Time: 18 ms (typical)

   – Program Time: 7 µs (typical)

• Auto Address Increment (AAI) for Rapid Factory Programming (High Voltage Enabled)

   – RY/BY# pin for End-of-Write detection

   – Multi-Byte Program

   – Chip Rewrite Time: (typical)

   - SST49LF004C: 1 seconds

   - SST49LF008C: 2 seconds

• Packages Available

   – 32-lead PLCC

   – 32-lead TSOP (8mm x 14mm)
