描述
The RL78/H1D microcontroller includes high precision analog functions such as Delta-Sigma A/D converter, SAR A/D converter, Programmable Gain amplifiers, Operational amplifier, and 8-bit/12-bit D/A converter. It also has a built-in LCD controller/driver which makes the RL78/H1D well suited for healthcare devices, especially blood pressure monitor.
