S71307-02-000 2/06 DEVICE MEMORY MAP FIGURE 3: DEVICE MEMORY MAP DESIGN CONSIDERATIONS SST recommends a high frequency 0.1 µF ceramic capac- itor to be placed as close as possible between VDD and VSS less than 1 cm away from the VDD pin of the device. Additionally, a low frequency 4.7 µF electrolytic capacitor from VDD to VSS should be placed within 1 cm of the VDD pin. If a socket is used for programming purposes, an addi- tional 1-10 µF should be added next to each socket. The RST# and INIT# pins must remain stable at VIH for the entire duration of an Erase or Program operation. WP# must remain stable at VIH for the entire duration of the Erase and Program operations for non-Boot Block sectors. To write data to the top Boot Block sectors, the TBL# pin must also remain stable at VIH for the entire duration of the Erase and Program operations. PRODUCT IDENTIFICATION The Product Identification mode identifies the device as the SST49LF004B and manufacturer as SST. 7FFFFH 70000H 6FFFFH 60000H 5FFFFH 50000H 4FFFFH 40000H 3FFFFH 30000H 2FFFFH 20000H 1FFFFH 10000H 0F000H 02000H 01000H 00000H Boot Block 4 KByte Sector 1 4 KByte Sector 2 4 KByte Sector 0 Block 7 Block 6 Block 5 Block 4 Block 3 Block 2 Block 1 Block 0 1307 F02.0 WP# Block 0-6 TBL# (64 KByte) TABLE 2: PRODUCT IDENTIFICATION Address Data PP Mode LPC Mode1 1. Address shown in this column is for boot device only. Address locations should appear elsewhere in the 4 GByte system memory map depending on ID strapping values on ID[3:0] pins when multiple LPC memory devices are used in a system. Manufacturer’s ID 0000H FFBC 0000H BFH Device ID2 2. The device ID for SST49LF004B is the same as SST49LF004A. SST49LF004B 0001H FFBC 0001H 60H T2.0 1307 |
