E-OCD II Interface Hardware
2.1
E-OCD II Interface
The E-OCD II interface supports ABOV 8-bit MCUs that use either the OCD or OCD II interface logic.
So, the user can perform debugging for both OCD and OCD II-compatible MCU series using this
hardware.
2.1.1
Features of E-OCD II H/W
The E-OCD II interface is the most cost-efficient debugging solution for the MCUs developed by
ABOV
Semiconductor Co., Ltd. The E-OCD II interface is a sophisticated debugging tool. It is s more flexible
and faster than the OCD interface with the following features:
Support Devices for ABOV’s 8bit MCUs
Support MC95/96 and A95/96 series devices
E-OCD II supports Debugging and on-board programming
E-OCD II Serial supports ISP via serial interface (DSCL, DSDA)
10-pin external connector for Debugging and programming
USB HID transmission is applied to Hardware of E-OCD II.
Include two interface lines: SCLK and SDATA, and one option line: RTIME (run time
measuring)
Can measure the exact operating time of the target MCU down to the microsecond range -
In this case, RTIME must be connected.
Cover the full range of the target device’s operating frequency
Supply power to the target MCU available.
Power out current consumption limit 50mA
Target system operating voltage : 3V ~ 6V
Low Level transmission 1.0V ~ 5.5V
E-
OCD II can debug full range of the target device’s operating frequency.
Enhanced protection circuitry for external I/O ports
512Byte expanded memory is added
Level Shift IC is added at DSCL, DSDA port for Low Level transmission
Support function for Power Out to Target B/D.
ESD Protection is advanced(2000V Human-Body, 200V Machine, 1000V Charged Device)
