San Jose, Calif. ZiLOG Inc. extends its Crimzon Infrared (IR) remote microcontroller (MCU) family with the launch of the ZLR64400 family of 8-bit MCUs. These 64 KB devices feature an "on-chip" capability to learn codes from other infrared remote controls for consumer products via a learning circuit.
Driven by growing demand for IR remote-controlled devices, ZiLOG determined a need for a larger on-chip database for better geographic, model, brand and device code coverage, which required more than 32 KB of ROM. In addition, the company integrated the learning capability, which typically has been external to the MCU, in these applications. This integration is expected to reduce development time as well as a customer's bill of materials by up to 15 percent.
Learning features are fast becoming a standard feature in mid- to high-end remote controllers, and the ability to capture an IR signal from any other remote control then duplicate it on the "learning" remote enables universal remote controls to consolidate several single device remotes and add codes from newly-purchased devices, said the company. Once the codes are captured, they are mapped to keys on the universal remote via integrated firmware.
The ZLR64400 also offers extra memory which can house larger amounts of data, and broadens device coverage for customers, said the company. It features 1 KB of general-purpose RAM and up to 64 KB of ROM, offering fast executing, efficient use of memory, sophisticated interrupts, input/output bit manipulation capabilities, automated pulse generation/reception, and internal key-scan pull-up transistors.

When used in combination with ZiLOG's proprietary IR code database, advanced compression techniques, development tools and project engineering support, the ZLR64400 is said to provide the most comprehensive "one-stop shop" for remote control development.
The ZLR64400 devices are fully software-compatible with ZiLOG's existing portfolio of Crimzon ROM-based IR microcontrollers. Development tools include the ZLP128ICE01ZEM emulator/programmer and ZiLOG Developer Studio II (ZDS II), which are available for programming and debugging.

Available immediately, the ZLR64400 is priced at $1.72 in quantities of 10,000.
