| Description | The AS4C4M16SA-7TCN is a high-speed 64Mbit synchronous DRAM (SDRAM) developed by Alliance Memory, designed for embedded systems and high-performance digital applications. It features a memory organization of 4M × 16 bits, enabling efficient parallel data access for processors, FPGAs, and SoC-based platforms. The device operates at a maximum clock frequency of 143 MHz with an access time of approximately 5.4 ns, delivering reliable high-speed performance for buffering and real-time data processing applications. Built on a fully synchronous architecture, all inputs and outputs are registered on the rising edge of the clock signal, ensuring stable timing and predictable operation. Internally, the SDRAM is organized into 4 banks, allowing concurrent operations and improved memory bandwidth. The AS4C4M16SA-7TCN supports advanced features such as programmable burst lengths (1, 2, 4, 8, full page), CAS latency (CL2/CL3), and sequential/interleaved burst modes, enabling flexible system optimization. It also includes auto-refresh, self-refresh, and power-down modes, ensuring data integrity and reducing system power consumption. Operating within a supply voltage range of 3.0V to 3.6V (typ. 3.3V), the device is compatible with standard logic systems and embedded designs. Housed in a compact 54-pin TSOP-II surface-mount package, the AS4C4M16SA-7TCN is ideal for space-constrained PCB layouts. It operates over a commercial temperature range of 0°C to +70°C, ensuring stable performance in typical environments. The AS4C4M16SA-7TCN is widely used in applications such as embedded systems, industrial controllers, networking equipment, display systems, consumer electronics, and FPGA/SoC memory expansion, where reliable and high-speed volatile memory is required. |
