Renesas SH7286 has memory for motor contol
The SuperH SH7286 offers up to 1Mbyte of fast MONOS embedded flash memory that has been designed specifically for the high-end drives, AC servos and general-purpose inverter markets.
Dual-core processor powers up to 1920MIPS
The new SH7786 incorporates dual SH-4A high-performance 32bit RISC CPU cores, each with a processing performance of 960MIPS at 533MHz.
The new models incorporate up to 1Mbyte of Flash memory capable of single-cycle access at the 50MHz maximum operating frequency.
A deep software standby mode has been provided as a first for the H8SX family, enabling standby power consumption to be further reduced.
Five Flash memory capacities of 256, 384, 512 and 768Kbyte and 1Mbyte are available.
The H8SX/1638 provides a pin-to-pin, upward compatible 1Mbyte Flash version to the ROM-less H8SX/1651,1650.
The line-up includes 120-pin and 144-pin standard package products, allowing a user to select the ideal model for any of a wide range of systems, from low-end to high-end.
Products in the PC, OA, digital consumer and industrial fields continue to offer a variety of new functions while facing demands for systems to be made smaller and inexpensive.
Renesas Technology has responded to this trend with the introduction of the H8SX family of high-performance 32bit CISC microcomputers.
The H8SX/1638 group and H8SX/1648 group comprise advanced products featuring many functions additional to those of the current H8SX family.
A maximum of three independently operable on-chip A/D convertor units enable A/D conversion time to be cut to as little as approximately one-quarter that of current Renesas products, while two 16bit-timer TPU (timer pulse unit) and PPG (programmable pulse generator) units enable various kinds of user system timer and pulse control to be implemented by a single chip.
In addition, 8bit timer input is now available as the clock source for the SCI (serial communication interface) inherited from current products, allowing flexible transfer rates to be implemented.
These features allow a user to select the optimal model for a particular system from a comprehensive product lineup, and simplify system upgrades such as functional enhancements.
The H8SX/1648 group comprises 144-pin package products featuring the addition of two I2C bus interface channels and four 10bit-resolution A/D convertor channels to the features of the H8SX/1638 Group.
The package line-up comprises a 120-pin LQFP for the H8SX/1638 Group, a 144-pin LQFP for the H8SX/1648 Group, all featuring a lead-free specification.
Samples are already available.
The H8SX/1638 and H8SX/1648 lineup are supported by Renesas' tool chain that includes the High Performance Embedded Workbench HEW, and the powerful low cost E10A-USB debugger.
It features full-speed debug in the user system connected via USB.
