Description

IS25WP080 is an 8Mbit (1Mbyte) 1.8V serial Flash memory device designed for compact systems requiring low pin count, low power consumption, and high-speed nonvolatile storage. It supports standard SPI, Dual I/O, Quad I/O, QPI, and DTR interfaces with read clock rates up to 133MHz and an equivalent QPI rate of 532MHz, along with 256-byte programmable pages, configurable drive strength, and more than 20 years of data retention. Typical applications include embedded code storage, execute-in-place (XIP) memory, consumer electronics, industrial equipment, and space-constrained systems requiring fast serial Flash memory.

• 532MHz equivalent QPI data rate
• DTR operation up to 66MHz
• 10mA typical active read current
• 8µA typical standby current
• 1µA typical Deep Power Down current
• 256-byte programmable page size
• Selectable dummy cycles
• Configurable output drive strength
• Supports SPI Modes 0 and 3

Pinout

Working Principle

• The IS25WP080 stores data in nonvolatile Flash memory cells and communicates with a host processor through a low-pin-count serial interface
• Standard SPI operation uses serial input, serial output, serial clock, and chip enable signals for command, address, and data transfers
• Dual and Quad I/O modes increase the number of data lines used during transfers to improve memory bandwidth
• QPI operation uses a four-bit wide interface to achieve an equivalent transfer rate of up to 532MHz at a 133MHz clock frequency
• DTR commands transfer addresses and read data on both clock edges to further improve effective data throughput
• Page programming supports up to 256 bytes per programmable page
• SFDP support allows compatible host controllers to obtain configurable Flash device parameters
• Deep Power Down mode reduces power consumption when the memory is not actively required

Design Notes

• Operate the device from a regulated 1.65V to 1.95V supply and maintain adequate local decoupling close to the V_CC and ground connections
• High-speed 133MHz operation requires careful PCB routing, short signal paths, controlled trace impedance, and appropriate signal integrity practices
• Use the appropriate dummy-cycle configuration for the selected read mode and operating frequency
• Configure the output drive strength according to PCB loading and signal integrity requirements rather than using unnecessarily high drive strength
• Keep Chip Enable control well defined during power-up, power-down, and reset conditions to prevent unintended commands
• Protect the Flash contents from unintended erase or program operations by properly controlling write-enable and status-register functions
• For XIP designs, select the appropriate Quad I/O, QPI, or DTR read configuration to balance throughput, latency, and controller compatibility

Applications

• Embedded code storage
• Execute-in-place (XIP) systems
• Consumer electronics
• Industrial control equipment
• Embedded controllers
• Digital audio and multimedia equipment
• IoT and connected devices
• Space-constrained electronic products
• High-speed serial memory interfaces

Working Principle

• The BTS7960 integrates a high-side p-channel MOSFET and a low-side n-channel MOSFET to form a complete half-bridge for driving inductive loads
• The integrated driver accepts logic level control signals from a microcontroller and automatically manages gate timing with built-in dead time generation
• PWM control regulates motor speed while active freewheeling improves efficiency and reduces switching losses
• The integrated current sensing function provides diagnostic feedback for monitoring motor load conditions
• Protection circuits continuously monitor operating conditions and automatically shut down the device during overcurrent, short-circuit, overtemperature, overvoltage, or undervoltage events
