• Manufacturer Part Number: upd70f3402
• Description: 32-/16-bit Single-chip Microcontroller With Can Interface
• Manufacturer: Renesas Electronics Corporation.

27.8.7 Bus interface timing (µPD70F3403, µPD70F3403A only)
CLKOUT Asynchronous (4.5 V
Notes: 1. T= t
Address setting time (to ASTB↓)
Address maintenance time (to ASTB↓) <15>
RD↓ → Address float delay time
Address → Data input setting time
RD↓ → Data input setting time
ASTB↓ → RD, WRn↓ delay time
Data input hold time (to RD↑)
RD↑ → Address output time
RD, WRn↑ → ASTB↑ delay time
RD↑ → ASTB↓ delay time
RD, WRn low level width
ASTB high level width
WRn↓ → Data output time
Data output setting time (to WRn↑)
Data output hold time (to WRn↑)
WAIT setting time (to Address)
WAIT maintenance time (to Address)
WAIT setting time (to ASTB↓)
WAIT maintenance time (to ASTB↓)
HLDRQ high level width
HLDAK low level width
HLDAK↑ → Bus output delay time
HLDRQ↓ → HLDAK↓ delay time
HLDRQ↑ → HLDAK↑ delay time
2. n shows the number of the wait clocks which is inserted in the bus cycle.
3. i shows idle state's number (0 or 1) which is inserted after the lead cycle.
4. This product doesn’t support CLKOUT synchronous mode.
In programmable wait insertion, sampling timing changes.
