ZLFBLST0P2064GR5621

Overview

The ZLFBLST0P2064GR5621 is a Crimzon RC Blaster system-on-chip microcontroller designed for universal infrared remote control applications. It integrates a 64K Flash memory, an IR engine, and the ZBase database to transmit signals via an external LED. The device supports two-way full-duplex UART communication at 9.6 kbps or 19.2 kbps, as well as software I2C up to 10 kbps. It operates on a low voltage supply ranging from 1.9 V to 3.6 V and includes four user-programmable GPIO pins.

Feature Summary

• Integrated 64K Flash memory with comprehensive North American and European IR code databases
• Supports IR learning functionality using a single photodiode and integrated amplifier
• Dual communication interfaces: Hardware UART (9.6/19.2 kbps) and Software I2C (up to 10 kbps)
• Four user-programmable General-Purpose Input/Output (GPIO) pins

Applications

• Set-top boxes (STB)
• Digital video recorders (DVR)
• DVD recorders
• IPTV systems
• Media center PCs

Procurement Notes

Verify the specific suffix '5621' against current manufacturer documentation, as it indicates the ROM code version at the time of ordering. Confirm package availability for the 20-pin PDIP configuration. Check for updated firmware or script upgrade support requirements for the target application.

Selection Notes

Select this component when a turnkey infrared solution with embedded database coverage is required. Ensure the design accommodates the 1.9 V to 3.6 V operating voltage range. Verify that the host CPU supports either UART or I2C protocols for command transmission. Consider the 20-pin PDIP package constraints for PCB layout.

Part Context

This part belongs to the Crimzon RC Blaster family of Universal Infrared (UIR) solutions manufactured by Zilog. It utilizes the ZBase infrared code database and an integrated learning algorithm. The 'P' in the part number specifies the 20-pin PDIP package variant within the broader product line.

Replacement Considerations

Other variants in the Crimzon RC Blaster family offer different packages such as SSOP, SOIC, or QFN. OTP and ROM versions are available but lack the flash memory for script upgrades. Verify pin compatibility if substituting with other package types.
