These provide power sequencing for the device and its I/O peripherals such as memories and SD cards, as well as provide battery charging capability for Li-Ion batteries. The i.MX28 processor includes an additional 128-Kbyte on-chip SRAM to make the device ideal for eliminating NXP reserves the right to change the detail specifications as may be required to permit improvements in the design of its products.Introduction external RAM in applications with small footprint RTOS. The i.MX28 supports connections to various types of external memories, such as mobile DDR, DDR2 and LV-DDR2, SLC and MLC NAND Flash. The i.MX28 can be connected to a variety of external devices such as high-speed USB2.0 OTG, CAN, 10/100 Ethernet, and SD/SDIO/MMC. 1.1 Device Features The following lists the features of the i.MX28: ARM926EJ-S CPU running at 454 MHz: 16-Kbyte instruction cache and 32-Kbyte data cache Arm embedded trace macrocell (CoreSight ETM9) Parallel JTAG interface 128 KBytes of integrated low-power on-chip SRAM 128 KBytes of integrated mask-programmable on-chip ROM 1280 bits of on-chip one-time-programmable (OCOTP) ROM 16-bit mobile DDR (mDDR) (1.8 V), DDR2 (1.8 V) and LV-DDR2 (1.5 V), up to 205 MHz DDR clock frequency with voltage overdrive Support for up to eight NAND Flash memory devices with up to 20-bit BCH ECC Four synchronous serial ports (SSP) for SDIO/MMC/MS/SPI: SSP0, SSP1, SSP2, and SSP3. SSP0 and SSP1 can support three modes,1-bit, 4-bit, and 8-bit, whereas SSP2 and SSP3 can support only 1-bit and 4-bit modes. 10/100-Mbps Ethernet MAC compatible with IEEE Std 802.3: Single 10/100 Ethernet with GMII/RMII Supporting IEEE Std 1588-compatible hardware timestamp Supporting 50-MHz/25-MHz clock output for external Ethernet PHY Two 2.0B protocol-compatible Controller Area Network (CAN) interfaces One USB2.0 OTG device/host controller and PHY One USB2.0 host controller and PHY LCD controller, up to 24-bit RGB (DOTCK) modes and 24-bit system-mode Pixel-processing pipeline (PXP) supports full path from color-space conversion, scaling, alpha-blending to rotation without intermediate memory access. SPDIF transmitter Dual serial audio interface (SAIF) to support full-duplex transmit and receive operations each SAIF supports three stereo pairs Five application Universal Asynchronous Receiver-Transmitters (UARTs), up to 3.25 Mbps with hardware flow control One debug UART operating at up to 115 Kb/s using programmed I/O 2 Two I C master/slave interfaces, up to 400 kbps i.MX28 Applications Processors for Automotive Products, Rev. 4, 10/2018 2 NXP Semiconductors
