Key Features:  
Industry leading asynchronous Dual-Port Static RAM (up to 15ns)  
Simultaneous memory access through two ports  
TTL compatible; 5V power supply  
Supports Interrupt arbitration schemes  
Bus Width can easily expand to over 18 bits by using both MASTER and SLAVE  
HD121 with on-chip port arbitration logic  
BUSY output flag on HD121; BUSY input flag on HD125  
Available packages: 52 – pin Plastic Lead Chip Carrier (PLCC)  
(0°C to 70°C) Commercial operating temperature available for access time of 15ns and above  
(-40°C to 85°C) Industrial operating temperature available for access time of 25ns  
Pin-to-pin compatible with conventional dual-port devices including IDT 70121, 70125  
Product Description:  
HBA’s Asynchronous Dual-Port (ADP I) Static RAM offers industry leading 0.25um process technology and 2K x 9 memory  
configuration. Both devices support two memory ports with independent control, address, and I/O pins that enable simultaneous,  
asynchronous access to any location in memory. System designer has full flexibility of implementing deeper and wider memory  
using the depth and width expansion features.  
The HD121 is a stand alone 18K-bit Dual-Port Static RAM or as a “MASTER” Dual-Port Static RAM with HD125 as a  
“SLAVE” Dual-Port Static RAM in 18-bit-or-more bus width application. No additional discrete logic is required when using the  
MASTER/SLAVE configuration to provide bus width expansion.  
These devices have low power consumption, hence minimizing system power requirements. They are ideal for applications such  
as data communication, telecommunication, multiprocessing, test equipment, network switching, etc.
