APPENDIX A
Difference Between Industry Standard and UT69RH051
The areas in which the UT69RH051 differs from the industry
standard will be covered in this section. In this discussion,
industry standard will be used generically to refer to all speed
grades including the 20MHz.
1.0 RESET
The UT69RH051 requires the RST input to be held high for at
least 24 oscillator periods to guarantee the reset is completed in
the chip. Also, the port pins are reset asynchronously as soon as
the RST pin is pulled high. On the UT69RH051 all portions of
the chip are reset synchronously when the RST pin is high during
a rising edge of the input clock. When coming out of reset, the
industry standard takes 1 to 2 machine cycles to begin driving
ALE and PSEN immediately after the RST is removed, but the
access during the first machine cycle after reset is ignored by the
processor. The second cycle will repeat the access and processing
will begin.
2.0 POWER SAVING MODES OF OPERATION
2.1 Idle Mode
Idle mode and the corresponding control bit in the PCON SFR
have not been implemented in the UT69RH051. Setting the idle
control bit has no effect.
2.2 Power Down Mode
Power down mode and the corresponding control bit in the PCON
register have not been implemented in the UT69RH051. Setting
the power down control bit has no effect. Also, the Power Off
Flag in the PCON has not been implemented.
3.0 ON CIRCUIT EMULATION
The On Circuit Emulation mode of operation in the industry
standard has not been implemented in the UT69RH051.
4.0 OPERATING CONDITIONS
The operating voltage range for the industry standard is
5V+20%. The operating temperature range is 0
°
C to 70
°
C. On
the UT69RH051, the operating voltage range is 5V+10%. The
operating temperature range is -55
°
C to +125
°
C.
