Compute Module Datasheet Copyright Raspberry Pi (Trading) Ltd. 2016 1 Introduction The Raspberry Pi Compute Module (CM1), Compute Module 3 (CM3) and Compute Module 3 Lite (CM3L) are DDR2-SODIMM-mechanically-compatible System on Modules (SoMs) containing processor, memory, eMMC Flash (for CM1 and CM3) and supporting power circuitry. These modules allow a designer to leverage the Raspberry Pi hardware and software stack in their own custom systems and form factors.

Compute Module Datasheet Copyright Raspberry Pi (Trading) Ltd. 2016 4 Mechanical Specification The Compute Modules conform to JEDEC MO-224 mechanical specification for 200 pin DDR2 (1.8V) SODIMM modules (with the exception that the CM3, CM3L modules are 31mm in height rather than 30mm of CM1) and therefore should work with the many DDR2 SODIMM sockets available on the market. (Please note that the pinout of the Compute Module is not the same as a DDR2 SODIMM module; they are not electrically compatible.

Compute Module Datasheet Copyright Raspberry Pi (Trading) Ltd. 2016 6 Electrical Specification Caution! Stresses above those listed in Table 4 may cause permanent damage to the device. This is a stress rating only; functional operation of the device under these or any other conditions above those listed in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

Compute Module Datasheet Copyright Raspberry Pi (Trading) Ltd. 2016 9 9.1 Peripherals GPIO BCM283x has in total 54 GPIO lines in 3 separate voltage banks. All GPIO pins have at least two alternative functions within the SoC. When not used for the alternate peripheral function, each GPIO pin may be set as an input (optionally as an interrupt) or an output. The alternate functions are usually peripheral I/Os, and most peripherals appear twice to allow flexibility on the choice of I/O voltage.

Compute Module Datasheet Copyright Raspberry Pi (Trading) Ltd. 2016 9.1.4 SD/SDIO Interface The BCM283x supports two SD card interfaces, SD0 and SD1. The first (SD0) is a proprietary Broadcom controller that does not support SDIO and is the primary interface used to boot and talk to the eMMC or SDX x signals.
Compute Module Datasheet Copyright Raspberry Pi (Trading) Ltd. 2016 9.6 Composite (TV Out) The TVDAC pin can be used to output composite video (PAL or NTSC). Please route this signal away from noise sources and use a 75 ohm PCB trace. Note that the TV DAC is powered from the VDAC supply which must be a clean supply of 2.5-2.8V. It is recommended users generate this supply from 3V3 using a low noise LDO.
