PRODUCT OVERVIEW
1-9
Six Programmable Timer
The S3C2510A has six programmable timers. Each timer has its related pin, which is shared with programmable
I/O function. Each timer can be programmed two operation mode. One is interval mode and the other is toggle
mode. In interval mode, the initial timer output is set to low and it is set to high for 1 cycle time when timeout is
reached. therefore the timer output is shaped like pulse wave. In toggle mode, the timer output is toggled when
timeout is reached.
Hardware Watchdog Timer
The S3C2510A includes a watchdog timer, which is capable of generating system reset when the timeout value is
reached. The time value is ranged up to 2^30 system clock cycles. The watchdog timer is used to reset and restart
the system when a system has failed due to software error or to wrong response of external device.
Programmable Interrupt Controller
The S3C2510A has one programmable interrupt controller, which arranges the 36 programmable interrupt sources
by the programmable priority. The interrupt controller supports 36 maskable interrupt sources, where 30 interrupts
are from internal interrupts and 6 interrupts are from external interrupts. The interrupt with the highest priority is
reported to the CPU.
Programmable I/O Port Controller
The S3C2510A has 64 programmable I/O ports, which can be used for another function. If another function is
enabled, its I/O functionality is disabled. Six external interrupt request, four external DMA request, four external
DMA acknowledge, six timer outputs, 21 SAR signals, and 15 UART signals are multiplexed with I/O function.
Each I/O port can be programmed as Input or Output.

C Controller
The S3C2510A has IIC controller, which enables the customer to implement a simple and cost effective inter-IC
connection. The IIC bus is a two-wire synchronous serial interface consisting of one data (SDA) and one clock
(SCL) line. The S3C2510A IIC controller operates in only single master mode.
