W26010A  
´ 16 HIGH-SPEED CMOS STATIC RAM  
64K  
GENERAL DESCRIPTION  
The W26010A is a high-speed, low-power CMOS static RAM organized as 65,536 ´ 16 bits that  
operates on a single 5-volt power supply. This device is manufactured using Winbond's high  
performance CMOS technology.  
The W26010A has an active low chip select, separate upper and lower byte selects, and a fast output  
enable. No clock or refreshing is required. Separate byte select controls (#LB and #UB) allow individual  
bytes to be written and read. #LB controls I/O1-I/O8, the lower byte. #UB controls I/O9- I/O16, the  
upper byte. This device is well suited for use in high-density, high-speed system applications.  
FEATURES  
· High speed access time: 15/20/25 nS (max.)  
· Low power consumption:  
- Active: 1.3W (max.)  
· All inputs and outputs directly TTL compatible  
· Three-state outputs  
· Data byte control  
· Single +5V power supply  
· Fully static operation  
- No clock or refreshing  
- #LB (I/O1- I/O8), #UB (I/O9- I/O16)  
· Available packages: 44-pin 400 mil SOJ and  
Type II TSOP

Notes:  
1. During this period, I/O pins are in the output state, so input signals of opposite phase to the outputs should not be applied.  
2. The data output from DOUT are the same as the data written to DIN during the write cycle.  
3. DOUT provides the read data for the next address.  
4. Transition is measured ±500 mV from steady state with CL = 5 pF. This parameter is guaranteed but not 100% tested.
