There are also plans to expand the line-up to a total of 20 models with the addition of 5.0V products and on-chip USB products by the end of 2007. These products offer compatibility with the current H8SX family, offering a flexible approach to system functional enhancements and version upgrades.
The new models incorporate up to 1 megabyte of flash memory capable of 1-cycle access at the 50MHz maximum operating frequency. A deep software standby mode*1 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 768 kbytes, and 1 Mbyte are available. The H8SX/1638 provides a pin-to-pin, upward compatible 1MB 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.
