Electrical
Characteristics
1. Description
The AT91R40008 microcontroller is a member of the Atmel AT91 16-/32-bit microcontroller family, which is based on the ARM7TDMI processor core. This processor has a
high-performance, 32-bit RISC architecture with a high-density, 16-bit instruction set
and very low power consumption. Furthermore, it features 256K bytes of on-chip
SRAM and a large number of internally banked registers, resulting in very fast exception handling, and making the device ideal for real-time control applications.
The AT91R40008 microcontroller features a direct connection to off-chip memory,
including Flash, through the fully-programmable External Bus Interface (EBI). An
8-level priority vectored interrupt controller, in conjunction with the Peripheral Data
Controller, significantly improves the real-time performance of the device.
The device is manufactured using Atmel’s high-density CMOS technology. By combining the ARM7TDMI processor core with a large, on-chip, high-speed SRAM and a
wide range of peripheral functions on a monolithic chip, the AT91R40008 is a powerful
microcontroller that offers a flexible and high-performance solution to many computeintensive embedded control applications.

Thermal and Reliability Considerations
Thermal Data
In Table 4-3, the device lifetime is estimated with the MIL-217 standard in the “moderately
controlled” environmental model (this model is described as corresponding to an installation in
a permanent rack with adequate cooling air), depending on the device Junction Temperature.
(For details see the section ”Junction Temperature” on page 5.)
Note that the user must be extremely cautious with this MTBF calculation: as the MIL-217
model is pessimistic with respect to observed values due to the way the data/models are
obtained (test under severe conditions). The life test results that have been measured are
always better than the predicted ones.

Junction Temperature
The average chip-junction temperature TJ in °C can be obtained from the following:
1.
T J = T A + ( P D × θ JA )
2.
T J = T A + ( P D × ( θ HEATSINK + θ JC ) )
Where:
• θJA = package thermal resistance, Junction-to-ambient (°C/W), provided in Table 4-4 on
page 5.
• θJC = package thermal resistance, Junction-to-case thermal resistance (°C/W), provided in
Table 4-4 on page 5.
• θHEAT SINK = cooling device thermal resistance (°C/W), provided in the device datasheet.
• PD = device power consumption (W) estimated from data provided in the section ”Power
Consumption” on page 4.
• TA = ambient temperature (°C).
From the first equation, the user can derive the estimated lifetime of the chip and thereby
decide if a cooling device is necessary or not. If a cooling device is to be fitted on the chip, the
second equation should be used to compute the resulting average chip-junction temperature
TJ in °C

Timing Results
The delays are given as typical values in the following conditions:
• VDDIO = 3.0V
• VDDCORE = 1.8V
• Ambient Temperature = 25° C
• Load Capacitance = 0 pF
• The output level change detection is 0.5 x VDDIO
• The input level is 0.8V for a low-level detection and is 2.0V for a high level detection.
The minimum and maximum values given in the AC characteristic tables of this datasheet take
into account the process variation and the design.
In order to obtain the timing for other conditions, the following equation should be used:
t = δT° × ⎛ ( δVDDCORE × t DATASHEET ) + ⎛ δVDDIO ×
⎝
⎝
∑( CSIGNAL × δCSIGNAL )⎞⎠ ⎞⎠
Where:
• δT° is the derating factor in temperature given in Figure 5-1.
• δVDDCORE is the derating factor for the Core Power Supply given in Figure 5-2 on page 7.
• tDATASHEET is the minimum or maximum timing value given in this datasheet for a load
capacitance of 0 pF.
• δVDDIO is the derating factor for the I/O Power Supply given in Figure 5-3 on page 8.
• CSIGNAL is the capacitance load on the considered output pin.(1)
• δCSIGNAL is the load derating factor depending on the capacitance load on the related output
pins given in Min and Max values in this datasheet.
The input delays are given as typical values.
Note:

The user must take into account the package capacitance load contribution (CIN) described in
Table 3-1 on page 3.

Due to internal synchronization of input signals, there is a delay between an input event and a
corresponding output event. This delay is 3(tCP) in Waveform Event Detection mode and 4(tCP)
in Waveform Total-count Detection mode. The inputs have to meet the minimum pulse width
