QzROM

QzROM using programmable memory PROM technology support technology miniaturization, you can create a new type of micro-controller. "Qz" represents the two main properties: "quick delivery" and "easy to program." Currently has four 720 series and 740 series 8-bit micro-controller chip to provide this QzROM. Renesas all future 4-bit and 8-bit micro-controller chip will be equipped with devices QzROM. New on-chip memory to help reduce costs and speed delivery of custom-programmed microcontroller. Embedded systems market expansion adds products to reduce costs and contribute to rapid mass production of micro-controller needs. New QzROM Renesas microcontrollers - Q means "quick delivery", z means "easy to program" - is an excellent solution. This 4-bit and 8-bit devices is the need to 48KB or smaller on-chip memory design the ideal choice. PROM QzROM is a technical support using the miniaturization process of programmable memory. It can make the price equivalent to the traditional mask ROM microcontrollers, while increasing high value-added features. QzROM Renesas microcontrollers can make the products previously programmed and not programmed blank product prices are equal. In fact, the same micro-controller can be used for the blank product and mass production, without the need for mask ROM models for sample evaluation, help reduce costs and save time. QzROM microcontrollers can be written only once, turnaround time (TAT) is short. We can receive delivery of the device ROM code (see Figure 2) about two weeks to complete this short interval helps to spend more time debugging and evaluation to ensure program quality. In addition, we developed a dedicated microcontroller QzROM production readiness plan can be delivered in 7 days, and other major type in LQFP packaged devices. QzROM microcontrollers for embedded systems has important value QzROM The main features include micro-controller, wide operating voltage, protection, lower power consumption and on-line writing function. Micro-controller can provide products with the same blank 5V (2.7 to 5.5V) or 3V (1.8 to 3.6V) operating voltage range. However, after carrying out programming, QzROM microcontrollers offer full scale of 1.8V to 5.5V operating voltage range, so these devices can be used for a wide range of applications. These devices, like flash microcontroller as a protective function. After the device is written, this highly effective anti-tampering features prevent the read-after-write. These devices can be unprotected in the form of delivery, additional data after the write protection. QzROM work used to reduce leakage current technology can reduce power consumption. The standby power consumption can be reduced to very low levels, which is portable and other battery-powered equipment is very beneficial. As the micro-controller on-chip memory is PROM, when the device is mounted on a board, you can use our support partners programmer to write. Memory blocks will soon be introduced into two products, you can only write once a block. This will help achieve the program and data points that will help achieve the program and data separation. For example, a block of application code can contain fixed, while the other blocks can be used to store data, according to the embedded system will use the occasion of flexible changes. Current Renesas microcontroller is delivered QzROM 740 series and 720 series of products, as well as other products. In addition, Renesas plans to expand the lineup of programmable microcontrollers, Renesas future and all of the four 8-bit devices will use QzROM type.
