Software configuration
Note: The “Equation” column in the table shows the specifications under the conditions DVCCM = 3.0 V to 3.6 V and
*CL = CAS latency
Note: The internal bus cycle is T=10ns minimum value when the guaranteed temperature is 0 to 70 degree.
The internal bus cycle is T=13.3ns minimum value when the guaranteed temperature is -20 to 85 degree.

DMCSCLK pin: CL = 15pF
Others: CL = 25 pF
AC measurement conditions
• The letter “T” used in the equations in the table represents the period of internal bus frequency (f
• Output level: High = 0.7 × DVCCM, Low = 0.3 × DVCCM
• Input level: High = 0.9 × DVCCM, Low = 0.1 × DVCCM
which is one-half of the CPU clock (f
DVCC1A = DVCC1B = DVCC1C = 1.4 to 1.6 V.
1. DVCC3IO × 0.7 ≤ SELDVCCM ≤ DVCC3IO
2. DVSSCOMx ≤ SELMEMC ≤ DVCC3IO × 0.3
3. DMCCLKIN pin connect to DVSSCOMx
