LC709006V-TLM-E

Overview

The LC709006V-TLM-E is a CMOS peripheral integrated circuit designed to expand the I/O capabilities of microcontrollers. It interfaces with the MCU via synchronous serial communication and provides 24-bit parallel I/O expansion. The device supports a wide operating voltage range from 2.0V to 6.0V. Key electrical parameters include a maximum output current of 12mA per pin. The component operates within a temperature range of -40°C to +85°C and is housed in an SSOP-16 package.

Feature Summary

• Supports 4-wire or 5-wire synchronous serial transmission and reception for efficient data exchange.
• Provides 24-bit parallel I/O ports with bit-level direction specification.
• Allows configurable output types, including CMOS and N-channel open drain modes.
• Enables port-based output voltage adjustment to match peripheral power levels.

Applications

• Microcontroller I/O expansion in embedded systems
• Portable electronic devices requiring low-power interface solutions
• Industrial control systems needing flexible I/O configuration

Procurement Notes

Verify the specific suffix 'TLM-E' against the manufacturer's official documentation to confirm package type and tape-and-reel specifications. Ensure the voltage grade matches the system requirements, as the standard part may have different voltage variants. Cross-reference the RoHS compliance status with the latest datasheet revision to meet environmental regulations.

Selection Notes

Select this component when a microcontroller requires additional general-purpose I/O lines beyond its native capacity. The synchronous serial interface minimizes pin usage on the host MCU. Consider the 12mA output drive capability for direct load driving or use external buffers if higher current is needed. Verify that the 2.0V to 6.0V supply range aligns with the target application's power architecture.

Part Context

This IC belongs to the LC70900x series of I/O expanders manufactured by onsemi. These devices are specifically engineered to bridge the gap between limited MCU pins and complex peripheral requirements. The series offers flexibility in I/O configuration, making it suitable for various consumer and industrial applications where space and pin count are constrained.

Replacement Considerations

Check for direct pin-to-pin replacements within the LC70900x family, such as the LC709004A, ensuring functional compatibility regarding I/O count and interface protocol. Verify that any substitute maintains the same voltage range and package dimensions to fit existing PCB layouts without redesign.
