Description and Introduction

128K x 36 SYNCHRONOUS PIPELINED STATIC RAM The IS61SP12836-133TQ is a high-speed synchronous SRAM manufactured by ISSI (Integrated Silicon Solution, Inc.). Below are the factual specifications, descriptions, and features of the device:

### **Specifications:**
- **Density:** 128Mbit (4M x 36)
- **Organization:** 4,194,304 words × 36 bits
- **Supply Voltage:** 3.3V (±10%)
- **Speed:** 133 MHz (7.5 ns access time)
- **Package:** 119-ball BGA (TQFP)
- **Operating Temperature Range:** Commercial (0°C to +70°C) or Industrial (-40°C to +85°C)
- **I/O Type:** Synchronous (pipelined or flow-through output options)
- **Refresh:** No refresh required (static operation)
- **Interface:** Synchronous with separate input and output registers

### **Descriptions:**
- The IS61SP12836-133TQ is a high-performance synchronous SRAM designed for applications requiring fast, low-latency memory access.
- It supports burst mode operation for efficient data transfer.
- The device is commonly used in networking, telecommunications, and high-speed computing applications.

### **Features:**
- **High-Speed Operation:** 133 MHz clock frequency with 7.5 ns access time.
- **Synchronous Design:** Supports pipelined and flow-through operation.
- **Burst Mode:** Linear or interleaved burst sequences (supports 2, 4, and full-page bursts).
- **Low Power Consumption:** Standby and sleep modes reduce power usage.
- **3.3V Power Supply:** Compatible with standard LVTTL/LVCMOS interfaces.
- **No Refresh Required:** Unlike DRAM, SRAM retains data without periodic refresh cycles.
- **Industrial-Grade Options:** Available in extended temperature ranges for harsh environments.

This information is based on the manufacturer's datasheet and technical documentation. For detailed electrical characteristics, timing diagrams, and application notes, refer to ISSI’s official documentation.

Application Scenarios & Design Considerations

128K x 36 SYNCHRONOUS PIPELINED STATIC RAM

Alternative Part Number

  • CY7C1354B-133AXC --: Pin-compatible synchronous SRAM with similar 128K x 36 organization and 133 MHz speed grade, widely used as a drop-in alternative to ISSI SRAMs.
  • MT55L128L36P1F-133 --: 128K x 36 synchronous pipelined SRAM at 133 MHz with comparable timing and interface, suitable functional replacement.
  • K7N163645M-133 --: 128K x 36 synchronous SRAM rated at 133 MHz with similar pinout and access characteristics, usable as an alternative source.
  • MT55L12836A-133 --: Same 128K x 36 synchronous SRAM density and 133 MHz operation, suitable drop-in functional replacement.
  • K6R4016V1D-TC13 --: Synchronous pipelined SRAM in the same density and speed class with comparable TQFP footprint, suitable as a functional drop-in substitute.
  • IS61LPS12836A-133TQ --: Same vendor family successor with equivalent 128K x 36 organization and 133 MHz timing, offering a close electrical match though from a different series prefix.
