DESCRIPTION
Initial preliminary release.
Clarifies that unused/unimplemented bits in the CAN MOVX SRAM read 0.
Corrected the t_MCS time period table.
Corrected multiplexed 2-cycle date memory CEO-3 read figure to show RD and WR inactive.
Corrected P5.2 and P5.3 pin descriptions.
Corrected description of sequence to activate the crystal frequency multiplier.
Corrected references to PQFP to read LQFP.
Added RSTOL timing information.
Official release (removed “preliminary” status).
Abs max soldering temp now references JEDEC standard.
AC and DC specifications updated to reflect final characterization data.
Clarified DC characteristics Note 6 concerning port 4 and 5.
Removed Figure 1. Typical I_CC vs. Frequency.
Added t_LLAX3 specification (identical to t_LLAX2).
Clarified that t_RLAZ is held weak latch until overdriven by external memory.
Removed t_PXIZ, t_PHAV, t_PHWL, and t_PHRL from nonmultiplexed address/data bus table.
Corrected PSEN trace in Figure 10 to not show assertion during MOVX write.
Corrected Table 3 to show unnecessary steps during 16/16 divide.
Supplied approximate oscillator-fail detection frequency.
Removed text references to Stop mode current.
Corrected location of PT2 in Table 14.
In Absolute Maximum Ratings section (page 2):
Removed “A” from IPC/JEDEC J-STD-020A specification to support lead-free devices.
In DC Electrical Characteristics table (page 2):
Changed V_PFW MIN to 4.10V from 4.20V
Changed V_PFW MAX to 4.60V from 4.55V
Changed V_RST MIN to 3.85V from 3.95V
Changed V_RST MAX to 4.35V from 4.3V
Changed V_IH2 MIN reference to 0.7 x V_CC from 0.7 x V_DD
Added Note 10
In AC Electrical Characteristics table (page 3):
Added note to (now) Note 11 that AC timing is characterized and guaranteed by design but
is not production tested.
Added lead-free part numbers to Ordering Information table.
Added new paragraph to page 33 stating “Software must ensure that the input value for the
normalize operation is not zero or the function will not complete. Compilers such as the one from
Keil Software have updated their libraries and compensate for this condition.”
Table 3: clarified text under “Normalize” function. Changed “Configure MCNTO register as
required.” to “Load MCNT0 with 00h.”
