For new Smartport Drive/FDD emulator
Due to some reasons, I've planned to develop faster Newer Smart Drive for APPLE II system.
The AVR(Atmega128) isn't fast compare to these days MPU and lack of memory.
Even AtXmega series are only 32Mhz.
For better performance for Smartport Drive and more function for DISK][,
I'm going to new design for new Smartport Drive and FDD emulator.
I have lots of choice but, I want to use one of not well known MPU.
It is Korean made one and good features has.
It is what I want to use.
Parameters | Values |
EISC Core | 32bit AE32000 |
F. Max (MHz) | 96 |
MIPS | 96 |
Vcc (V) | 3.3 |
Packages | Pb-Free |
100 TQFP | |
Flash (Kbytes) | 128/512 |
SRAM (Kbytes) | 80 |
NAND Flash Controller | 8bit I/O |
1/4bit ECC | |
SRAM Interface | 8/16 bit |
ISP | Yes |
JTAG | Yes |
PLL | Yes |
GPIO | 53 |
KEYSCAN | 4 X 4 |
External Interrupt | 2 |
DMA | 2 |
TIMER | 32bit x 8 |
SD Card Controller | Yes |
SPI | 1 |
TWI | 1 |
UART | 8 |
I2S | 1 |
Voice Codec | Yes |
ADC | Voice codec 14bit x 4 |
DAC | Voice codec 14bit x 1 |
RTC | Yes |
Watchdog Timer | 32bit |
USB | 2.0 Full (12Mbps) Device |
Control/Bulk/Interrupt |
And more USB and even RTC(Real time clock) there.
It has dedicate SD card controller so, it handle SD memory card with superb speed.
And this processor isn't exactly ARM processor but as followed the maker engineer, It based on the ARM technologies.
I've tested SD card Reading speed, It has more than 2MB/S.
I will update what I'm going to do.
This time. I can show testing board.
