Description and Introduction

Wide Temperature Range Version 4M High Speed SRAM (256-kword ′ 16-bit) The HM62W16255HCJPI-12 is a high-speed CMOS synchronous dynamic RAM (SDRAM) manufactured by HIT (Hyundai Electronics, now part of SK Hynix).  

**Key Specifications:**  
- **Type:** 16M x 16-bit (256Mb) SDRAM  
- **Speed Grade:** -12 (12ns access time, 83MHz operating frequency)  
- **Voltage:** 3.3V ± 0.3V  
- **Package:** 66-pin TSOP-II (Thin Small Outline Package)  
- **Refresh:** 4096 refresh cycles every 64ms  
- **Burst Length:** Programmable (1, 2, 4, 8, or full page)  
- **CAS Latency:** 2 or 3 (programmable)  
- **Operating Temperature:** Commercial (0°C to +70°C)

Application Scenarios & Design Considerations

Wide Temperature Range Version 4M High Speed SRAM (256-kword ′ 16-bit)

Alternative Part Number

  • IS61WV25616BLL-10TLI --: 256K x 16 asynchronous SRAM with 10 ns access time, functionally compatible with the 12 ns original and widely available.
  • CY7C1041CV33-10ZXI --: 256K x 16 low-power SRAM in TSOP package with comparable speed grade, suitable drop-in replacement for most designs.
  • AS7C34096A-10TIN --: 512K x 8 SRAM offering similar timing and voltage, usable as an alternative when address organization is adapted.
