Multicore flash mcus launched
1 min read
Renesas Electronics has brought two new 32bit All Flash microcontrollers to market. The parts, which have been added to the V850 mcu range, are said to offer a processing performance of 1024 Dhrystone MIPS at 200MHz).
The µPD70F3514 and 3515 feature dual cpus, 64kbyte of ram for each core, 1 or 2Mbyte of flash respectively and a further 64kbyte of system ram. Peripherals include USB, CAN and Ethernet interfaces, as well as an increased number of channels for conventional peripherals such as timers and serial interfaces.
By enhancing the pipeline structure of the V850E2 cpu core, Renesas has strengthened the parallel processing capability. The enhanced version, the V850E2M core, supports 2.56 Dhrystone MIPS/MHz/core, 1.4 times better than that of the V850E2 core.
With two V850E2M cores, system designers can take advantage of high processing performance, while consuming 0.88mW per Dhrystone MIPS.
System designers can choose either a single core or dual core mcu product, each mcu employing Renesas Electronics' V850E2M cpu core with robust processing capability. Renesas Electronics believes these new mcus will contribute to development of competitive systems for the fields of FA, industrial drives, printers and home appliances.
Renesas has also unveiled two single core variants, the µPD70F3510 and 3512, each with the V850E2M core and 1Mbyte of flash. The µPD70F3512 also features a 10/100 Ethernet controller.
