ALM1108YB8-7

Specialized ICS Overview

The ALM1108YB8-7 is a programmable mixed-signal IC from Diodes Incorporated, housed in an 8-pin X1-QFN1012-8 (Type AX) package. It operates within a supply voltage range of 1.71 V to 5.50 V and supports temperatures from -40°C to 85°C. The device features six digital I/O pins, including one dedicated input (IO2). Internal resources include two 2-bit LUTs, nine multifunctional macrocells, three 8-bit timers, a 16-bit timer, oscillators, and a Continuous Register Verification (CRV) system for data protection.

Specialized ICS Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure compatibility with the required tape and reel packaging format. Confirm that the programmed configuration matches the intended application logic before deployment.

Specialized ICS Selection Notes

Select this component for low-power asynchronous designs requiring hardware-defined logic without firmware overhead. Ensure the design fits within the available macrocell count and connection matrix constraints. Verify that the 1.71 V minimum operating voltage aligns with the system power rails.

Specialized ICS Part Context

The ALM1108 belongs to the μASIC family, designed as a flexible alternative to fixed ASICs and microcontrollers. It allows timing and event sequences to be updated via programming software changes while maintaining hardware-level reliability through direct matrix connections.

Specialized ICS Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Evaluate other programmable mixed-signal ICs based on pin count, voltage range, and logic resource availability if replacement is necessary.

Specialized ICS FAQ

What is the maximum supply voltage for the ALM1108?

The maximum recommended operating supply voltage (VDD) is 5.50 V.

Can all digital I/O pins function as outputs?

No, IO2 is restricted to Digital Input only. Pins IO3, IO4, IO6, IO7, and IO8 can function as both inputs and outputs.

What is the purpose of the Continuous Register Verification (CRV)?

CRV enhances functional reliability by continuously verifying the integrity of the internal registers.
