Elan Microelectronics Corp. is principally engaged in the research, development, manufacture and marketing of integrated circuits (ICs) and microcontrollers. The Company provides five categories of products: consumer ICs, including handwriting identification ICs, electronic education learning aid (ELA) ICs, high-second voice synthesis ICs, music ICs, computer ICs and controller ICs for remote controllers and small home appliances; communications ICs, including Walky talky wafers and other wafers for telephones; microcontrollers, applied for small home appliances, washing machines, air conditioners, communications products and remote controllers; personal computer peripheral ICs, such as touch controllers, keyboard ICs and others, as well as network interface devices (NIDs), including pointing sticks and touch pad modules. The Company distributes its products in Taiwan, Southeast Asia, Northeast Asia, the Americas and Europe.
Dallas Semiconductor was acquired by Maxim Integrated.
Dallas Semiconductor was founded in 1984 as a designer and manufacturer of semiconductors and chip-based subsystems. Dallas Semiconductor quickly established its innovation and technical leadership in developing a wide variety of high-performance products, including 1-Wire®, iButton®, microcontroller (MCU), timekeeping, thermal management, and communications devices.

ELAN Microelectronics clones (13 bit)
ELAN Microelectronics Corp. make a series of PICmicro-like microcontrollers with a 13-bit instruction word.[11] The instructions are mostly compatible with the mid-range 14-bit instruction set, but limited to a 6-bit register address (16 special-purpose registers and 48 bytes of RAM) and a 10-bit (1024 word) program space.
The 10-bit program counter is accessible as R2. Reads access only the low bits, and writes clear the high bits. An exception is the TBL instruction, which modifies the low byte while preserving bits 8 and 9.
The 7 accumulator-immediate instructions are renumbered relative to the 14-bit PICmicro, to fit into 3 opcode bits rather than 4, but they are all there, as well as an additional software interrupt instruction.
There are a few additional miscellaneous instructions, and there are some changes to the terminology (the PICmicro OPTION register is called the CONTrol register; the PICmicro TRIS registers 1–3 are called I/O control registers 5–7), but the equivalents are obvious Silicon Wafer Delayer & SEM Microphoto.
