AP0101CS HDR: Image Signal Processor (ISP)
General Description
General Description
The ON Semiconductor AP0101CS is a high-performance, ultra-low power in-line,
digital image processor optimized for use with High Dynamic Range (HDR) sensors. The
AP0101CS provides full auto-functions support (AWB and AE) and Adaptive Local Tone
Mapping (ALTM) to enhance HDR images and advanced noise reduction which enables
excellent low-light performance.
Functional Overview
Figure 1 shows the typical configuration of the AP0101CS in a camera system. On the
host side, a two-wire serial interface is used to control the operation of the AP0101CS,
and image data is transferred using the parallel bus between the AP0101CS and the host.
The AP0101CS interface to the sensor also uses a parallel interface.

System Interfaces
Figure 2 on page 5 shows typical AP0101CS device connections.
All power supply rails must be decoupled from ground using capacitors as close as
possible to the package.
The AP0101CS signals to the sensor and host interfaces can be at different supply voltage
levels to optimize power consumption and maximize flexibility. Table 4 on page 7
provides the signal descriptions for the AP0101CS.

Notes:
1. This typical configuration shows only one scenario out of multiple possible variations for this sen-
sor.
2. ON Semiconductor recommends a 1.5kresistor value for the two-wire serial interface R
PULL
-
UP
;
however, greater values may be used for slower transmission speed.
3. RESET_BAR has an internal pull-up resistor and can be left floating if not used.
4. The decoupling capacitors for the regulator input and output should have a value of 1.0uF. The
capacitors should be ceramic and need to have X5R or X7R dielectric.
5. TRST_BAR connects to GND for normal operation.
6. ON Semiconductor recommends that 0.1F and 1F decoupling capacitors for each power supply
are mounted as close as possible to the pin. Actual values and numbers may vary depending on lay-
out and design consideration
