1. Overview

MMC host interface

 Interface to multi-media card (MMC)

 Data bus: 1-/4-/8-bit MMC mode

 Interrupt requests: card detection, error/time-out, and normal operation

 DMA transfer requests: CE_DATA write and CE_DATA read

 Card detection function

General I/O ports

 256-pin: 115 I/Os, 8 inputs with open-drain outputs, and 16 inputs (input only)

 324-pin: 147 I/Os, 8 inputs with open-drain outputs, and 16 inputs (input only)

 Input or output can be selected for each bit.

A/D converter

 12-bit resolution

 Eight input channels

 Minimum conversion time: 5.0 μs

 A/D conversion request by the external trigger or timer trigger

Motor control PWM timer

 Two 10-bit PWM channels, each with eight outputs

Debugging interface

 Arm CoreSightTM architecture

 JTAG-standard pin assignment

On-chip RAM

 10-Mbyte (RZ/A1H) or 5-Mbyte (RZ/A1M) large capacity memory for video display/recording and

work (128 Kbytes are used for data retention)

 128-Kbyte memory for data retention

(16 Kbytes × 2, 32 Kbytes × 1, 64 Kbytes × 1)

Boot modes

 Five boot modes

Boot mode 0: Booting from memory (bus width: 16 bits) connected to the CS0 space

Boot mode 1: Booting from memory (bus width: 32 bits) connected to the CS0 space

Boot mode 2: —

Boot mode 3: Booting from a serial flash memory

Boot mode 4: Booting from a NAND flash memory with SD controller

Boot mode 5: Booting from a NAND flash memory with MMC controller

Power supply voltage

 Vcc: 1.10 to 1.26 V

 PVcc: 3.0 to 3.6 V
