The RL78/H1D is a new application specific standard product (ASSP) of the RL78 Family of MCU. The RL78/H1D, designed to control systems required for blood pressure measurement with a single chip. It incorporates rich analog functions including high-resolution delta sigma A/D converters, programmable gain instrumentation amplifiers, D/A converters, operational amplifiers, and other circuits required for blood pressure measurement, as well as timers for PWM (pulse-width modulation) control.

In addition to the delta sigma 24-bit A/D converters, the RL78/H1D also provides 10-bit sequential comparison A/D converters that operate asynchronously. This simplifies implementation of systems providing temperature measurement and battery voltage monitoring while measuring the blood pressure.

The rich analog functions make the new ASSP ideal not only for blood pressure monitoring systems but also for a wide array healthcare application including biosensors.

Samples of the RL78/H1D ASSP are available now. Pricing varies depending on the memory capacity, package and number of pins. For example, the R5F11NMG 80-pin LQFP package type with 128 KB flash ROM capacity is priced at US$3.50. The R5F11NMG includes an LCD controller for arm- and wrist-type blood pressure monitors, and a 4mm x 4 mm miniature ball grid array (BGA) package for use in wearable devices. (Pricing and availability are subject to change without notice.)
