Renesas Enhances H8SX 32-Bit CISC Microcontroller Series, Adding Three Product Groups that Offer More Performance, New Features.New Devices in the H8SX Series Provide up to 1 MB of Single-Cycle-Access on-Chip Flash Memory, Power-Saving Deep Standby Mode A sleep mode in a portable computer that provides an almost immediate resumption of operation when turned back on. In standby mode, the hard disk and display are turned off, and the CPU is throttled down to its lowest-power state. , Precision A/D Converter (Analog/Digital converter) A device that converts continuously varying analog signals from instruments and sensors that monitor conditions, such as sound, movement and temperature into binary code for the computer. , and More SAN JOSE, Calif. -- Renesas Technology America, Inc. today announced the enhancement of its popular 32-bit CISC (Complex Instruction Set Computer) Pronounced "sisk." The traditional architecture of a computer which uses microcode to execute very comprehensive instructions. (Complex Instruction Set Computer) microcontrollers with the addition of three new product groups. The eight devices in the H8SX/1638, H8SX/1648, and H8SX/1622 groups operate at up to 50MHz (MegaHertZ) One million cycles per second. It is used to measure the transmission speed of electronic devices, including channels, buses and the computer's internal clock. A one-megahertz clock (1 MHz) means some number of bits (16, 32, 64, etc. , achieve performance levels up to 50 MIPS (Million Instructions Per Second) The execution speed of a computer. For example, .5 MIPS is 500,000 instructions per second; 100 MIPS is a hundred million instructions per second. , and have extensive arrays of on-chip peripheral functions. The microcontrollers enable office automation products, digital consumer devices and industrial equipment that are more capable, smaller and less expensive. They offer up to 1 Megabyte of fast (zero-wait-state) on-chip flash memory that allows single-cycle access at 50MHz operation. A deep software standby mode(a)1 -- a first for H8SX devices -- achieves extra power savings, providing operation similar to that of software standby mode with only partial retention of RAM data. Additionally, the devices have faster and more precise analog input interfaces such as analog-to-digital (A/D A/D See advance-decline line (A/D). ) and delta-sigma(a)2 ([eth]o[eth]u) type A/D converters. Improved capabilities for handling signals from analog sensors Members of the H8SX/1638 series have two successive-approximation type 10-bit A/D converter units, each with 4 channels, while members of the H8SX/1648 series have three such units. Each of these A/D units operates independently for greater design flexibility. Conversion time has been reduced to 2osec, enabling faster system response in motion control, image processing and other types of embedded applications that obtain parameter data from analog sensors. By contrast, the microcontrollers in the H8SX/1622 group have only one 10-bit successive-approximation A/D converter with 8 channels. However, they also incorporate a 6-channel 16-bit delta-sigma type A/D converter with a conversion speed of 90.5osec at 25MHz operation. The higher-resolution delta-sigma A/D generates more precise data from optical, positional, acceleration, and sound sensors, among others. The fast analog conversion capabilities and the power optimization characteristics make the H8SX/1622 devices ideal for applications such as medical monitors, handheld consumer electronics products, power tools, robotics, and automobiles. Other peripheral functions built into the new H8SX-series chips include 8-bit timers, 16- or 32-bit programmable pulse generators, watchdog timers, serial communication interfaces, 2 or 4 channels of I2C bus interface, and clock pulse generators with multiplication phase locked loops (PLLs). All of the new microcontrollers have space-saving, lead-free packages: a 120-pin LQFP See QFP. (14mm x 14mm) for H8SX/1638 chips, a 144-pin LQFP (20mm x 20mm) for H8SX/1648 group devices, and a 144-pin LQFP or a smaller 145-pin LGA LGA abbr. large for gestational age LGA Large for gestational age, see there (9mm x 9mm) for H8SX/1622 microcontrollers. Support tools are available to facilitate the system design process. Renesas offers an integrated development environment See IDE. integrated development environment - interactive development environment with software tools, evaluation boards, and the low-cost Renesas E10A on-chip debug To correct a problem in hardware or software. Debugging software means locating the errors in the source code (the program logic). Debugging hardware means finding errors in the circuit design (logical circuits) or in the physical interconnections of the circuits. emulator.

Notes: 1. Deep software standby mode: A mode that provides operation similar to that in software standby mode (with only partial retention of RAM data) while achieving lower power consumption. 2. Delta-sigma A/D converter: In this type of analog interface circuit, analog data is converted to a bit stream by oversampling Creating a more accurate digital representation of an analog signal. In order to work with real-world signals in the computer, analog signals are sampled some number of times per second (frequency) and converted into digital code. then undergoes delta modulation, integration processing, and noise cancellation by means of filtering, and is converted to digital data.
