External memory controller
Controls access of externally connected devices such as ROM (FLASH), SRAM, SDRAM (EDO DRAM), IO
devices, and internal FLASH memory.
(1) ROM (FLASH) access function
: 1 bank
Supports 16-bit devices.
Supports FLASH memory:
Byte write (can be written only by IF equivalent to SRAM).
In ML67Q4002/ML67Q4003, control internal FLASH access.
Configurable access timing.
(2) SRAM access function
: 1 bank
Supports 16-bit devices.
Supports asynchronous SRAM
Configurable access timing.
(3) DRAM access function
: 1 bank
Supports 16-bit device
Supports EDO/SDRAM
: Simultaneous connections to EDO-DRAM and SDRAM cannot be
made.
Configurable access timing.
(4) External IO access function
: 2 banks
Supports 8-bit/16-bit access
: Independent configuration for each bank
Each bank has two chip selects
: XIOCS_N[3:0]
Supports external wait input
: XWAIT
Access Timing configurable for each bank independently
Power Management
HALT, STANDBY, clock gear, clock control functions are supported as power save functions.
(1) HALT mode
HALT object
CPU, internal RAM, AHB bus control
HALT mode setting: Set by the system control register.
Exit HALT mode due to: Reset, interrupt
(2) STANDBY mode
Stops the clock of entire LSI.
STANDBY mode setting: Specified by the system control register.
Exit
STANDBY mode due to: Reset, external interrupt (other than EFIQ_N)
(3) Clock gear
This LSI has two clock systems, HCLK and CCLK. Configure HCLK and CCLK frequency.
HCLK: CPU, bus control, synchronous serial interface, I2C.
CCLK: Timers, PWM, UART, AD converter, etc.
(4) Clock control by each function unit
AD converter, PWM, Timers, DRAMC, DMAC, UART(FIFO), UART, Synchronous SIO, I2C.
