Operational Description
eZ80L92 Development Kit
User Manual
eZ80L92 Module Memory
Reset Generator
IrDA Transceiver
The eZ80L92 Module contains 512KB SRAM and 1MB Flash memory.
This addressing structure provides 1MB of contiguous SRAM for imme-
diate use.
SRAM Memory
The eZ80L92 Module features 512KB of fast SRAM. Access speed is
typically 12ns or faster, allowing zero-wait-state operation at 48MHz.
With the CPU at 48MHz, onboard SRAM can be accessed with zero wait
states in eZ80 mode. CS1_CTL (chip select CS1) can be set to
wait states).
Flash Memory
The Flash Boot Loader, application code, and user configuration data are
held permanently in Flash memory. As an example, for 128KB onboard
SRAM, 1MB of ROM is required.
The onboard Reset Generator Chip is connected to the eZ80L92 Reset
input pin. It performs reliable Power-On Reset functions, generating a
reset pulse with a duration of 200ms if the power supply drops below
2.93V. This reset pulse ensures that the board always starts in a defined
condition. The RESET pin on the I/O connector reflects the status of the
RESET line. It is a bidirectional pin for resetting external peripheral com-
ponents or for resetting the eZ80L92 Development Kit with a low-imped-
ance output (e.g. a 100-Ohm push button).
An onboard IrDA transceiver (ZiLOG ZHX1810) is connected to PD0
(TX), PD1 (RX), and PD2 (Shutdown, IR_SD). The IrDA transceiver is
of the LED type 870nm Class 1.
