Introduction of the HL5310 GPIO Expander
HMI, a prominent name in advanced analog and power management, has recently announced the launch of its HL5310 model. This new ultra-low voltage 12-bit GPIO expander is crafted to cater to the demands of modern microcontrollers while focusing on efficiency and flexibility.
Key Features of the HL5310
The HL5310 is specifically designed for enhancing remote I/O expansion through the Fast-mode Plus (Fm+) I²C-bus interface, which allows for communication speeds of up to 1MHz. What truly sets the HL5310 apart is its capability to work efficiently with microcontrollers running from as low as 1.0V. This innovative feature ensures that engineers have more flexibility in their design choices.
Flexible Power Options
One of the standout characteristics of the HL5310 is its incorporation of separate power rails. The device utilizes VDD_I²C, VDD_P0, and VDD_P1 for the I²C-bus, along with six 6-bit I/O ports that support a voltage range from 1.0V to 5.5V. This flexibility not only allows for diverse system configurations but also facilitates the creation of mixed power systems, where the power supply to the I²C bus can differ from that of the I/O ports.
Innovative Programming Capabilities
Programming the 12-bit I/O ports on the HL5310 has been simplified significantly. Users can easily set up various configurations such as input polarity, pull-up/pull-down resistors, and interrupt functionalities. The device supports advanced interrupt functions that include level and edge triggering, as well as the ability to mask, clear, and monitor status efficiently. Additionally, the HL5310 is equipped with a debounce function tailored for systems that experience noisy inputs, which helps improve reliability.
Enhanced Output Configurations
For output configurations, the HL5310 offers selectable push-pull or open-drain output stages. Moreover, it includes four programmable drive strengths that optimize rise and fall times, ensuring that devices can react swiftly and accurately to I/O demands from the system it integrates with.
Compliance and Availability
The HL5310 adheres to RoHS and Green standards, assuring buyers of its environmentally-friendly construction. Coupled with its compact 20-bump WLCSP package measuring just 1.82mm x 1.47mm with a 0.35mm pitch, it’s evident that HMI has prioritized both performance and space-saving design in the creation of this product.
Statement from HMI's Leadership
Mason Choi, the VP and GM of HMI, remarked, "Introducing the HL5310 reflects our dedication to fostering innovation within power management solutions. With its ultra-low voltage capabilities and flexibility in applications, we are confident the HL5310 will transform how engineers approach I/O expansion in their designs."
