128M bits Mobile RAM
EDL1216CASA (8M words × 16 bits)
Description
Pin Configurations
The EDL1216CA is a 128M bits Mobile RAM organized
as 2,097,152 words × 16 bits × 4 banks. The Mobile
RAM achieved low power consumption and high-speed
data transfer using the pipeline architecture. All inputs
and outputs are synchronized with the positive edge of
the clock.
This product is packaged in 54-ball FBGA (µBGA).

VDDQ: 1.8V ± 0.15V
• Wide temperature range (−25°C to 85°C)
• Programmable partial self refresh
• Programmable driver strength
• Programmable temperature compensated self refresh
(Option)
• Deep power down mode
• Small package (54-ball FBGA (µBGA))
• Fully Synchronous Dynamic RAM, with all signals
referenced to a positive clock edge
• Pulsed interface
• Possible to assert random column address in every
cycle
• Quad internal banks controlled by BA0 and BA1
• Byte control by LDQM and UDQM
• Wrap sequence = Sequential/ Interleave
• /CAS latency (CL) = 2, 3
• Automatic precharge and controlled precharge
• Auto refresh and self refresh
• ×16 organization
• 4,096 refresh cycles/64ms
• Burst termination by Burst stop command and
Precharge command
• FBGA(µBGA) package is lead free solder (Sn-Ag-Cu)
Applications
Mobile cellular handsets, PDAs, wireless PDAs,
handheld PCs, home electronic appliances, and
information appliances, etc.
/xxx indicates active low signal.

Precharge command (/CS, /RAS, /WE = Low, /CAS = High)
This command begins precharge operation of the bank selected by BA0 and BA1. When A10 is High, all banks are
precharged, regardless of BA0 and BA1. When A10 is Low, only the bank selected by BA0 and BA1 is precharged.
After this command, the Mobile RAM can’t accept the activate command to the precharging bank during tRP
(precharge to activate command period). This command corresponds to a conventional DRAM’s /RAS rising.
