数字电源管理IC内置微控制器 MD6603的概要
The MD67xx series, our digital management ICs, incorporate the MD6603 whose functionality is optimized for digital power supplies.
The MD6603 is an 8-bit MCU (Microcontroller Unit) optimal for power control applications including digital power supplies.
In addition to the 8-bit CPU, the MD6603 consists of two 16-bit TnyDSP units?a very unique configuration?and thus brings smart but low-current-consumption control into any power control applications requiring with high-speed arithmetic processing.
What’s more, equipped with extensive analog functions and robust system support functions (e.g., the high-resolution PWM module), the MD6603 will help your power control application achieve higher efficiency and performance.

Built-in MCU MD6603: 4 Key Features
-
Feature 1: Extensive Analog Functions
The analog functions built in the MD6603 include fast 12-bit AD converters (4 MSPS; 2 units), comparators with reference voltage generators, and general-purpose operational amplifiers. Programmable interconnection is available among the analog functions, or between the analog functions and external pins.
-
Feature 2: Sophisticated DSP-based Arithmetic Processing by 4 Core Processors Incl. CPU
Besides the main CPU and 2 units of 16-bit TinyDSP, the MD6603 has the EPU (Event Processing Unit) inside. This EPU is an arithmetic unit that can parallelly process 6 threads (channels) with low latency.
So, the MD6603 is capable of parallel processing with these processors: the CPU for system processing, the TinyDSPs for arithmetic processing, and the EPU for complex real-time processing.
-
Feature 3: High-resolution PWM Function
The MD6603 integrates the PWM module, whose output waveform has a resolution of 1 ns, and can set both duty cycles and cycles.
In addition, the PWM module offers the automatic dead time addition function, and performs a fast response to a duty cycle cut or cycle cut of PWM waveforms synchronized with external events such as a comparator.
-
Feature 4: Inter-peripheral-register Automatic Data Transfer (DSAC)
The MD6603 allows automatic data transfer among the registers of the built-in peripheral functions.
For example, when data is automatically transferred among the AD converters, TinyDSPs, and PWM module, the feedback control without the CPU is then enabled. During this feedback control, the CPU can focus on system processing (e.g., abnormality detection, communication processing).

Compact Debug Interfaces “OCD I/F Board”
We offer a debug interface “OCD I/F board” which connects a PC and a target board for program development.
So you don’t need expensive ICE or JTAG debuggers anymore!
Our OCD I/F board only requires a USB to connect your PC, and 3 wires to connect the target board. With these connections, you can debug the programs in the flash memory.
We have also released the circuit diagram of this OCD I/F board.
