насчёт RTC точно не знаю - у меня NSC PC87591L c Y2K-compliant RTC.

Designed specifically for notebook PCs, the PC87591 features the typical keyboard controller functions such as internal keyboard matrix scan and decode, as well as acting as an interface between the external keyboard and mouse. In addition, the PC87591 can secure the PC by utilizing an on-chip random number generator to implement advanced password protection, BIOS integrity checking, and memory protection.
The PC87591 utilizes a high performance 16-bit RISC processor and a large 2MB address space for easy integration of concurrent functions - a necessity in today's competitive notebook market. This means that the PC87591 can implement the normal keyboard and mouse functions of a standard keyboard controller -- implementing advanced power-savings modes to prolong battery life in the notebook PC and add full battery charging and conditioning software and firmware. At the same time, the PC87591 can take over additional functions like controlling the CD drive in the notebook to allow users to listen to their music, even when the notebook PC is powered down.

The H8S/2140B Group are microcomputers (MCUs) made up of the H8S/2000 CPU, and the peripheral functions required to configure a system.
The H8S/2000 CPU has an internal 32-bit configuration, sixteen 16-bit general registers, and a simple and optimized instruction set for high-speed operation. The H8S/2000 CPU can handle a 16-Mbyte linear address space.
This LSI is equipped with a data transfer controller (DTC) as a bus master, ROM, RAM, an 8-bit PWM timer (PWM), a 14-bit PWM timer (PWMX), a 16-bit free-running timer (FRT), an 8-bit timer (TMR), timer connection, a watchdog timer (WDT), a serial communication interface (SCI), a keyboard buffer controller, a host interface X-bus interface (XBS), a host interface LPC interface (LPC), an 8-bit D/A converter, a 10-bit A/D converter, and I/O ports as on-chip peripheral modules required for system configuration. An I2C bus interface (IIC) can also be included as an optional interface.
A high-functionality bus controller is also provided, enabling fast and easy connection of DRAM and other kinds of memory.
H8S/2148 Group and H8S/2149, H8S/2169 Group implement extended functions.
