Units Notes
Notes:
1. Nominal VCC_CORE is 1.6v.
2. V
REF
:
V
REF
is nominally set by a (1%) resistor divider from VCC_CORE.
The suggested divider resistor values are 90.9 ohms over 80.6 ohms to produce a divisor of 0.47.
The internal V
REF
(V
REF-INT
) is the external V
REF
scaled by 0.80 (V
REF-INT
= (V
REF
/0.80)). (Processor pin SysVrefMode = High)
Given: VCC_CORE = 1.6V, V
REF
= 752mV (1.6 * 0.47), V
REF-INT
= 940mV (752mV/0.8).
Peak-to-Peak AC noise on V
REF
(AC) should not exceed 2% of V
REF
(DC).
3. I
VREF
should be measured at nominal V
REF.
4. V
OL-DC-MAX,
V
OL-AC-MAX,
V
OH-DC-MIN
and V
OH-AC-MIN
are specified at T = 100
°
C and VCC_CORE = 1.4V.
5. Does not apply to V
REF
.
6. The following signals have twice the capacitance because they connect to two input pads
SDATAINCLK[3:0]# and SYSCLK,
SYSCLK#.
SDATAINCLK[3:0]# connects 2 byte clocks to form a word sized clock. SYSCLK connects to CLKIN/RSTCLK. SYSCLK# connects to
CLKIN#/RSTCLK#
7.
Measured at maximum VCC_CORE = 1.70 V
The maximum power supply current must be taken into account when designing a
power supply.
