TSMU818A030ACQ

Overview

The TSMU818A030ACQ is an eight-channel parametric measurement unit (PMU) featuring 18-bit resolution and a 30V force voltage span. It supports up to 100mA output current with programmable ranges from ±5µA to ±100mA using external sense resistors. The device integrates channel-independent DACs, including 18-bit force, 16-bit offset, and 15-bit clamp DACs. It operates within a 0°C to +100°C temperature range and utilizes an SPI-compatible interface with an 80MHz clock for fast updates. The component is housed in a 144-pin FCBGA package.

Feature Summary

• Eight independent channels supporting FV, FI, FZ, MV, and MI functions
• 18-bit force DAC with multiple voltage ranges and offset/gain calibration
• Programmable current ranges up to ±100mA with external RSENSE
• Stable operation with capacitive loads up to 10µF

Applications

• Memory test systems
• Semiconductor test equipment
• Source measurement units

Procurement Notes

Verify the specific ordering suffix ACQ corresponds to the 144-pin FCBGA package configuration. Confirm production status and moisture sensitivity level ratings prior to procurement. Ensure compatibility with the required JEDEC tray packaging specifications for the target manufacturing process.

Selection Notes

Select this PMU for applications requiring high-resolution multi-channel parametric testing. Evaluate the need for external sense resistors to achieve the maximum ±100mA current range. Consider the 144-pin FCBGA footprint and thermal management requirements for the 0°C to +100°C operating environment during PCB layout.

Part Context

This component belongs to the TSMU818A030 series of parametric measurement units. It shares functional similarities with other devices in the family but differs in package options, such as the 196-pin AMO variant. The ACQ suffix specifically denotes the 144-FCBGA package type used in this part number.

Replacement Considerations

The TSMU818A030AMO serves as a pin-compatible alternative within the same series, offering identical electrical performance in a 196-pin FCBGA package. Verify board space constraints when considering this substitution.
