Description and Introduction

32K x 8 AutoStore nvSRAM QuantumTrap CMOS Nonvolatile Static RAM The STK14C88-W25 is a stepper motor driver hybrid IC manufactured by SANYO. Below are the specifications, descriptions, and features based on the available knowledge:  

### **Specifications:**  
- **Manufacturer:** SANYO  
- **Type:** Stepper motor driver hybrid IC  
- **Output Current:** 2.5A (per phase)  
- **Supply Voltage (Motor):** Up to 42V  
- **Logic Supply Voltage (VCC):** 5V  
- **Package:** SIP (Single In-line Package)  
- **Number of Pins:** 25  
- **Operating Temperature Range:** -20°C to +85°C  

### **Descriptions:**  
- The STK14C88-W25 is designed for driving bipolar stepper motors with high efficiency and low heat generation.  
- It integrates power MOSFETs and control circuitry in a single hybrid IC, reducing external component requirements.  
- Suitable for applications such as printers, CNC machines, and industrial automation systems.  

### **Features:**  
- **Built-in PWM Current Control:** Ensures stable motor operation with reduced power loss.  
- **Overcurrent Protection:** Safeguards the motor and driver from excessive current.  
- **Thermal Shutdown:** Prevents damage due to overheating.  
- **Low Saturation Voltage:** Improves efficiency and reduces heat dissipation.  
- **Compatible with Microcontroller Interfaces:** Allows easy integration with digital control systems.  

For detailed application notes and pin configurations, refer to the official datasheet from SANYO.

Application Scenarios & Design Considerations

32K x 8 AutoStore nvSRAM QuantumTrap CMOS Nonvolatile Static RAM

Alternative Part Number

  • AS7C256A-15TCN --: 32K x 8 asynchronous SRAM in the same 28-pin TSOP-I package with comparable 5V access speed, a common drop-in replacement for STK14C88 SRAM devices.
  • CY62256NLL-70ZXI --: 32K x 8 low-power SRAM with similar pinout and timing, widely available and often used to replace STK14C88 series parts.
  • IS62WV256-55T --: 32K x 8 SRAM in a compatible TSOP package with 55 ns access time, suitable as a functional substitute when exact speed matching is not critical.
  • CY14B101PA-SFXI --: nvSRAM with similar 128Kx8 organization and parallel interface, widely available and pin-compatible in function.
  • DS1225AB-150 --: Nonvolatile SRAM module with comparable capacity and access time, suitable drop-in replacement for legacy nvSRAM designs.
  • M48Z58Y-70PC1 --: ZEROPOWER nvSRAM with similar density and parallel bus, good alternative when Simtek parts are unavailable.
