• Manufacturer Part Number: st2601b
• Description: 8-bit Integrated Microcontroller
• Manufacturer: Sitronix Technology Corporation

details and notice when using external bus by ST2600B in two mode: (1)Stand alone mode (2) ICE-mode
(1) When using ST2600B Stand alone mode:
(2) When using ST2600B ICE mode:
< Pull-up resistance of D0~D7 for current issue when using ST75xx >
Description: When entering sleep mode, D0~D7 of ST75xx will be floating, and make current consumption (about 120uA). It
External memory bus can be output directly by ST2600B DVB (PCB-300) J22 pin-1 to pin-32
Because external data can be controlled by PC through ST-ICE, so the external bus will be shared with ICE connector
pins (PCB-300 - J15)
(a) Please first amount 74hc32 on U11 and U12.
(b) PCB-300 J15 pins allocation as following:
(c) ST2600B DVB should be connected to ST-ICE by J15, and also be connected to external bus by above
can be solved by adding 8 1M-ohm resistance on D0~D7.
