IDT70V7278S/L  
32K x 16 BANK-SWITCHABLE  
DUAL-PORTED SRAM WITH  
EXTERNAL BANK SELECTS  
Features  
32K x 16 Bank-Switchable Dual-Ported SRAM Architecture  
– Four independent 8K x 16 banks  
Interrupt flags with programmable masking  
Dual Chip Enables allow for depth expansion without  
external logic  
UB and LB are available for x8 or x16 bus matching  
LVTTL-compatible, single 3.3V (±5%) power supply  
Available in a 100-pin Thin Quad Flatpack  
Industrial temperature range (-40° to +85°C) is available  
for selected speeds  
– 512 kilobit of memory on chip  
Fast asynchronous address-to-data access time: 15ns  
User-controlled input pins included for bank selects  
Independent port controls with asynchronous address &  
data busses  
Four 16-bit mailboxes available to each port for inter-  
processor communications; interrupt option

NOTES:  
1. The first six address pins for each port serve dual functions. When MBSEL = VIH, the pins serve as memory address inputs. When MBSEL = VIL, the pins serve as mailbox  
address inputs.  
2. Each bank has an input pin assigned that allows the user to toggle the assignment of that bank between the two ports. Refer to Truth Table I for more details.
