San Jose, Calif. - A "tiny" family of microcontrollers from Atmel Corp. features on-chip flash, E2PROM and analog capabilities. The tiny11, tiny12, tiny15 and tiny28 are all priced below a dollar in high volume.
The same flash-based microcontroller can be used for design, prototype evaluation and volume production, eliminating the need for ROM and one-time programmable alternatives, said Jim Panfil, director of microcontroller products. "Whatever program changes are needed can be made on the fly, so we eliminate the scrap associated with OTP or mask ROM," he said.
The tiny11 targets motor control, external logic and switch replacement. The tiny12, with an internal RC oscillator, is intended for security and surveillance, remote keyless entry and industrial-control applications. The tiny15, suited for light ballast, battery chargers, smart-battery packs and sensors, includes a four-channel, 10-bit analog-to-digital converter. All three MCUs have 1 kbyte of flash and 64 bytes of E2PROM.
The tiny28, for universal remote control with infrared LED, includes a high-current driver and programmable modulation. It has 2 kbytes of flash and no E2PROM. The tiny11, 12 and 15 come in eight-pin packages; the tiny28 comes in a 28-pin package.
Panfil said that the parts benefit from Atmel's ability to integrate nonvolatile memory, logic and analog blocks on one chip, with room left over for end-of-the-line personalization. The operating and programming voltages can be as low as 1.8 V.
