San Jose, Calif.Renesas Technology America Inc. has added 16Kbyte flash versions to its line-up of low pin count SH/Tiny flash microcontrollers.
According to Renesas, the lower memory versions provide a more flexible and cost-effective product with many advantages over DSPs. With their performance and small memory sizes, the devices perform both real-time control and DSP functions.
The SH/Tiny flash MCU family already includes pin-compatible 32Kbyte, 64Kbyte and 128Kbyte derivatives which have 8KByte RAM. The new 16Kbyte version includes 4Kbyte of RAM, making it the lowest cost flash-based SuperH device in the portfolio.
The family is available in a wide line-up of packages, including 10x10mm 64LQFP, 14x14mm 64QFP, 10x10mm 48LQFP, and the ultra-tiny 8x8mm 64VQFN and 7x7mm 52VQFN packages. The devices offer fast MONOS (Metal Oxide Nitride Oxide Silicon) embedded flash enabling fully deterministic zero-wait operation rated at 65MIPS. The SH2 32-bit RISC CPU core has 16 general-purpose 32-bit registers and a 32x32=64 hardware MAC unit.
The SH/Tiny devices also have a sophisticated MTU2 timer unit with six channels of 16-bit timers, support for up to 16 input capture/output functions capacity, as well as a three-phase PWM capability for electrical motors.
The SH/Tiny line-up has been developed for white goods applications such as induction cooking, washing machines, vacuum cleaner motor control and inverters such as in pumps, fans and air-conditioning (HVAC). The 16Kbyte version is ideally suited for these applications.
