EP7309
High-Performance, Low-Power System on Chip
FEATURES
OVERVIEW
The EP7309 is designed for ultra-low-power operation. Its core
operates at only 2.5 V, while its I/O has an operation range of
2.5 V–3.3 V. The device has three basic power states:
operating, idle and standby.
MaverickKey unique hardware programmed IDs are a solution
to the growing concern over secure web content and
commerce. With Internet security playing an important role in
the delivery of digital media such as books or music,
traditional software methods are quickly becoming unreliable.
The MaverickKey unique IDs provide OEMs with a method of
utilizing specific hardware IDs such as those assigned for
SDMI (Secure Digital Music Initiative) or any other
authentication mechanism.

The EP7309 integrates an interface to enable a direct
connection to many low cost, low power, high quality audio
converters. In particular, the DAI can directly interface with
the Crystal‚ CS43L41/42/43 low-power audio DACs and the
Crystal‚ CS53L32 low-power ADC. Some of these devices
feature digital bass and treble boost, digital volume control and
compressor-limiter functions.
Simply by adding desired memory and peripherals to the
highly integrated EP7309 completes a low-power system
solution. All necessary interface logic is integrated on-chip.
— CODEC Sound Interface
— 88 Keypad Scanner
— 27 General Purpose Input/Output pins
— Dedicated LED flasher pin from the RTC
Internal Peripherals
— Two 16550 compatible UARTs
— IrDA Interface
— Two PWM Interfaces
— Real-time Clock
— Two general purpose 16-bit timers
— Interrupt Controller
— Boot ROM
Package
— 208-Pin LQFP
— 256-Ball PBGA
The fully static EP7309 is optimized for low power
dissipation and is fabricated on a 0.25 micron CMOS
